		<description><![CDATA[Guest blogger Bill O'Donnell does an in-depth review of his newly acquired Canon EOS 5D Mark II with some sample photos.]]></description>
			<content:encoded><![CDATA[<p>Wow, the <a href="http://www.bhphotovideo.com/c/product/583953-REG/Canon_2764B003_EOS_5D_Mark_II.html/BI/2448/KBID/3281">Canon 5D Mark II</a> (<a href="http://www.bhphotovideo.com/c/product/583987-REG/Canon_2764B004_EOS_5D_Mark_II.html/BI/2448/KBID/3281">kit with Canon EF 24-105mm f/4L IS USM</a>) is an unbelievable camera and I strongly encourage everyone to take a look at this camera. According to dxomark, <a href="http://www.dxomark.com/index.php/eng/DxOMark-Sensor">http://www.dxomark.com/index.php/eng/DxOMark-Sensor</a> the 5D2 is rank 4<sup>th</sup> among some very expensive cameras. Based on it score, I believe the 5D2 is a much better deal.</p>
<p>Now to be honest with you all, I don’t consider myself a professional photographer, but rather it just a hobby of mine. I have read many of the reviews and many of the comparisons between other cameras and I have to say my 3 weeks of experience with this camera certainly lines well with the reviews. I have no real way to compare the 5D2 with any of the more interesting camera such as the Canon 50D, 1D3, or the Nikon D3. There are plenty of other reviews available that covers this angle of the 5D2 story. I have not seen much real life reviews of the camera, so I figure I take this opportunity to write a review based on real life conditions. To put things in the proper context, I am upgrading from the Canon EOS Rebel XT. I had considered upgrading to the 40D, but I felt that it was not enough bang for me to upgrade. The Canon 5D Mark II offered the bang I was looking to achieve and I truly believe it was worth every penny.<span id="more-2442"></span></p>
<p>I view myself as a generalist and do not focus on one area of photography. I have one camera (new 5D2) and a bunch of L lenses for the camera. If there is a picture to take, I take it and so far, I found the Canon 5D Mark II to be able to handle just about any thing. The camera is not just for weddings!</p>
<p>In this review, I will share some photo I have taken so far as well as cover my favorite features of the camera. Most of my sample photos will be JPEG right from the camera with the NR set to standard. In the past, I would shoot RAW and I would post process my RAW with Bibble Pro 4.10. But at this time, Bibble does not support the 5D2 as of yet and the DPP is frankly too slow for me. I have recently considered changing to Photoshop, but I have decided that I rather buy a new L lense then pay for PhotoShop. I have a license for Bibble and it a great product and will just have to wait until Bibble can support the 5D2. Certainly, I have RAW versions of all my photos and plan on experimenting with Cropping and evaluating its NR capabilities with the 5D2 once Bibble Pro 5 comes out with 5D2 support. Lucky for me, the 5D2 is producing awesome JPEG pictures right out of the camera which is allowing me to wait.</p>
<p>First up is Indoor Basketball shoots. I have hundreds of them so far. This one was taken in bad lighting conditions in an old gym. I used my Canon 24-70 F2.8 Lens with an Exposure Time of 1/250Sec, F-Stop 2.8, and ISO 3200. This photo came right out of the camera with no adjustments. The white balance is great and the colors are perfect. It has some noise, but certainly this can easily be clean up.</p>
<p><a href="http://bui4ever.com/files/2009/01/image001.jpg"><img class="aligncenter size-medium wp-image-2448" src="http://bui4ever.com/files/2009/01/image001.jpg" alt="" width="607" height="405" /></a></p>
<p>Here is another shot in a gym where the lighting conditions where much better. I used my Canon 24-70 F2.8 Lens again with an Exposure Time of 1/320Sec, F-Stop 3.2, and ISO 1600. This photo came right out of the camera with no adjustments. The white balance is great and the colors are perfect. Interesting in this gym, I have the camera set to Tv Priority set at 1/320 and auto ISO enabled. What I like about the 5D2 is that the F-stop will float between 3.2 and 2.8 (not sure why) but more importantly, the ISO will adjust down and low as possible (which I like a lot). For this lighting condition, the ISO seems to float between 1000 and 2500. The lighting changes slightly depending on where I am sitting in the gym and how far I have zoomed in or out the lens.</p>
<p><a href="http://bui4ever.com/files/2009/01/image002.jpg"><img class="aligncenter size-medium wp-image-2449" src="http://bui4ever.com/files/2009/01/image002.jpg" alt="" width="606" height="404" /></a></p>
<p>This next shot I had the camera set to full automatic. I don’t always use full automatic, but I wanted to see what the 5D2 would do in this condition. The 5D2 use ISO 100, F-stop of 8, and Exposure of 1/640 Sec. I used my Canon 70-200 F4 IS lenses for this shoot.</p>
<p><a href="http://bui4ever.com/files/2009/01/image003.jpg"><img class="aligncenter size-medium wp-image-2450" src="http://bui4ever.com/files/2009/01/image003.jpg" alt="" width="607" height="405" /></a></p>
<h3>DIGIC 4 imaging processor</h3>
<p>Comparing the 5D2 with my old Canon EOS Rebel XT (350D), one of the first things you will notice is the imaging processor capabilities in the 5D2. It seemed that just about every picture I had taken with the Rebel XT, needed some adjustments to the photo and why I always shot RAW. I had to adjust the White Balance, noise for ISO 800 or 1600, and at times, even the color was not quite right. However with the new DIGIC 4 image processor, I am seeing the colors and the white balance more under control and even more exciting, it has a built in Noise Reduction capability. Unscientifically of course, if you compare the JPEG coming right out of the camera, you notice a major difference in over all quality.</p>
<p>Being a Full Frame camera, right off the bat, you will notice a 1 F-Stop advantage over a crop camera such as the Rebel XT in respect to controlling the Exposure Time. In addition, using DPP and reviewing RAW files and comparing old basketball photo I had at 1600 and comparing them with the new basketball photo I have with the 5D2, I can notice the difference right away. The 350D at 1600 was not always usable. It depended a lot on the lighting conditions. With the 5D2, I am finding that noise level to be very usable up through 6400. To be clear, I do not have formal comparisons (kinda hard to do that with low lighting indoor action sports), but certainly I have been able to clean up a few 6400 test shots I have taken that simply look great. Many times I struggled when using 1600 on the 350D.</p>
<p>The other problem I had with the 350D, is I would set Av priority to a F-Stop of 2.8 and set the ISO to 1600. Many times, I would get blurry pictures because at times, the Exposure Time would be under 1/160 Sec. I did experiment with the under exposing with result of even more noise to deal with. Hard to get a half way decent indoor basketball shoot with bad gym lighting conditions and getting undesirable Exposure Times. Trust me, been there, done that. The 5D2 now gives me the ability to take great shoots even when the lighting conditions are bad.</p>
<p>Wow, for me, one of the biggest things I noticed with the 5D2 is the battery life between charges. When I had my 350D, it had to always have a 2<sup>nd</sup> battery with me especially when I used AI SERVO. With the 5D2 and using AI SERVO, I am taking hundreds of shots and coming home with my battery still having 70% or 80% battery power remaining. I could not be any happier here. I almost bought a 2<sup>nd</sup> battery for the 5D2, but the sales guy was very honest and said that I may not need it based on why I had a second one for the 350D. He was correct. I appreciate the honesty I got from them at <a href="http://www.cameracompany.com/">www.cameracompany.com</a>.</p>
<p>In addition, the 5D2 offers the ability to give you Battery status information such as the percentage remaining and the number of shots remaining. The 350D did not have this ability. In respect to basketball photos I have been taking, I found the Auto Focus with AI SERVO enable to be really fast as compare to the 350D I am use too. Many times with the 350D, I would loose a shot because the Auto Focus was simply not ready and fast enough. For the 5D2, I have yet to miss a picture I wanted; always focused and ready to go.</p>
<p>For a guy like me who is over 40 now, the screen on the 350D was just becoming a problem for me. The 5D2 3” LCD Screen is not only much bigger, but it also very sharp. The two things you need when you’re over 40. So if your over 40, this screen is a must have. Similar to the 350D, it does offer the ability to zoom in and out when reviewing photos, but what different is that the photo remains sharp as you zoom in. Also, it has a very nice button that they call their multi-controller which allows mouse like ability to move your picture up and down or left to right, very easily.</p>
<h3>Menu System</h3>
<p>Bottom line, it is very easy and simple! Just the way I like it. In addition, I was able to customize my very own screen. The only negative I will say is when I took the Ski photo above, I discovered that the customize Screen is not available if you are in full auto mode. For me, I don’t use full Auto Mode very often, but I do think this is a ridiculous restriction that Canon should consider removing. In respect to the 350D, the menu system is a major improvement with the 5D2.</p>
<h3>Continues Shooting</h3>
<p>The 5D2 has the ability to take 3.9 Shots per second which is slightly faster then the 350D. The 50D can perform at 6.3 shots per second with the 40D slightly faster. Given that some of my pictures are indoor sports, I debated for some time if I should go with the 50D or the 5D2. At the end, I went with the 5D2 because of the much better sensor that can handle low lighting conditions much better then the 50D. Putting the sensor to the side, simply having the 1 stop advantage being a full frame camera means you can basically double your Exposure time which is important for indoor sports pictures. I have never tried using a 50D or a 40D, but so far, I have been able to get great actions shots without the 6.3 advantage.</p>
<h3>Video</h3>
<p>So far, it appears to be working very well. I felt it was important to mention it, but at this point in time, I have not spent a lot of time using it in some real world scene.</p>
<h3>Black Dots</h3>
<p>Given all of the buzz about black dots, I thought it was important to mention the situation. The 5D2 can produce black dots that can be seen when shooting in very low lighting and you are taking a picture of street lights or Christmas lights. Based on what I read, they can be seen when you crop the photo by 100%. If you look closely, you will see a black dot in the middle of the light. Good news is Canon has acknowledged the problem and plans a firmware upgrade at some point to address the problem. My personal view is I have never seen the issue with my camera but then again, I never had an opportunity to take pictures on the conditions required to see this problem.</p>
<h3>Final Thoughts</h3>
<p>I am sure you can tell that I am quite pleased with this camera. 5D2 is an awesome camera. I feel the 5D2 has a solid control of its noise performance up to ISO 6400. I now have the ability to take much improved indoor sport pictures. I am sure the Nikon D3 or 700 or the Canon 1D3 can take solid indoor sport pictures as well, but given the price point and where I am as a hobbyist today, the 5D2 is a create camera and great option for me.</p>

			<content:encoded><![CDATA[<p>This was a free two hour class offered by Canon and Keeble &amp; Shuchat with <a href="http://jenniferwu.com/">Jennifer Wu</a> about Canon&#8217;s L lenses by Jim Rose and nature photography tips from Jennifer. I originally heard about this from Jim when he came to COBA to <a href="http://bui4ever.com/2008/08/cps-shutterbudd-and-adobe-photoshop-lightroom-2-discussions/">discuss about CPS membership</a>. As an added treat, Canon brought twenty four L lenses, including the Canon EF 500mm f/4L IS USM and the Canon EF 800mm f/5.6L IS USM, and five bodies (three 1D Mark IIIs, one 1Ds Mark III, one Canon XSi, and a Canon EOS 5D) for everyone to try. Also Jim brought a pre-production Canon EOS 50D with the new Canon EF 18-200mm f/3.5-5.6 IS zoom lens.<span id="more-2006"></span></p>
<div id="attachment_2008" class="wp-caption alignnone" style="width: 735px"><img class="size-large wp-image-2008" src="http://bui4ever.thebuicompany.com/files/2008/09/canon-l-series-lenses-02-725x483.jpg" alt="Canon EOS 1D Mark III with Canon EF 800mm f/5.6L IS USM" width="725" height="483" /><p class="wp-caption-text">Canon EOS 1D Mark III with Canon EF 800mm f/5.6L IS USM</p></div>
<h3>The Canon L Series Lenses</h3>
<p>The class started off with Jim Rose discussing about what makes Canon &#8220;L&#8221; lenses so special from the normal consumer level lenses. He also confirmed that the &#8220;L&#8221; does, in fact, stand for Luxury. What defines a L lenses is the existence of:</p>
<ul>
<li>Two or more Ultra-Low Dispersion (UD) elements (and/or)</li>
<li>Fluorite Element (and/or)</li>
<li>Ground and polished aspherical elements</li>
</ul>
<p>Fluorite is a natural occurring element, but usually not enough in quantity to be useful, so Canon has developed a method to &#8220;grow&#8221; them. It takes at least two ultra-low dispersion to equal one fluorite element. The fluorite element eliminates almost all chromatic aberrations.</p>
<p>Wide angle lenses and &#8220;fast&#8221; lenses (f/1, f/1.2, f/1.4, f/1.8, f/2) experience <a href="http://en.wikipedia.org/wiki/Spherical_aberration">spherical aberrations</a> which causes the images not to be as sharp until they are stopped down to apertures of f/5.6 or f/8. By using aspherical elements, this counter-acts the spherical aberration effect and can also make zoom lenses smaller in size. There are three types of aspherical elements:</p>
<ul>
<li>Molded aspherical element: round glass is super heated until near melting and is poured into a molding and allowed to cool thus making a molded aspherical element. This process makes creating aspherical elements cheaper, but not as good quality.</li>
<li>Replicated aspherical element: a piece of specially created resin is glued to the round glass to create an aspherical element. This types of aspherical element tends to appear in the consumer grade Canon lenses</li>
<li>Ground and polished aspherical: glass is grounded and polished until they meet the aspherical criteria. Very expensive and appears exclusively in the L line.</li>
</ul>
<p>The Canon L lenses are designed to be durable withstanding: torrential down pour rain, extreme temperatures, snow, grueling wear and tear. All the L lenses use ring type Ultra Sonic Motor (USM) focus motors. This is the fastest type of auto focus that Canon has. Jim also spoke of the f/4 zooms (17-40mm, 24-105mm, and 70-200mm) and offering customers a choice in lighter weight equipment at a lower price with the same L quality. Jim also spoke briefly of Canon&#8217;s &#8220;S&#8221; line, the EF-S mount lenses specially designed for the crop sensors.</p>
<p>Jim also spoke of the tilt-shift lens and it&#8217;s uniqueness in the Canon line. Also someone in the audience had asked why only one of the three tilt-shift lenses offered by Canon is designated as a L and Jim&#8217;s response was: 1) L designation is given to lenses who fit the above requirements and 2) not all lenses require fluorite or ultra-low dispersion glass to achieve optimal quality. Thus, the 45mm and 90mm tilt-shift lenses are not L quality lenses because they do not contain fluorite or ultra-low dispersion elements.</p>
<h3>Nature&#8217;s Elusive Beauty</h3>
<p><img class="size-medium wp-image-2026 hang-2-column alignright" src="http://bui4ever.thebuicompany.com/files/2008/09/canon-l-series-lenses-020-495x329.jpg" alt="Jennifer Wu" width="495" height="329" /></p>
<p>Jennifer Wu gave a great PowerPoint presentation on capturing Nature&#8217;s Elusive Beauty, the one moment in which the scene is perfect, the lighting is just right, the colors are popping, the scene is ready to be captured.</p>
<p>Jennifer shoots with a new Canon EOS 1Ds Mark III and a Canon EOS 5D. Her lenses are the Canon EF 17-40mm f/4L USM, Canon EF 16-35mm f/2.8L USM, Canon EF 24-70mm f/2.8L USM, and the Canon EF 70-200mm f/2.8L IS USM. She does very little post processing, usually dodging and burning and does not remove anything from the scene with Adobe Photoshop or up the saturation in anyway. She uses a circular polarizer and neutral density filters.</p>
<p>Some of the bullet point tips she offered:</p>
<ul>
<li>Finding locations: Internet, guide books, asking the locals</li>
<li>Things to consider: seasons, fall colors at peaks, when flowers are in bloom</li>
<li>Get local advice: call ranger stations (rangers have most likely hiked every inch of the area and done it repeatably where they would know the best times to visit), visitor shops to find the answer to questions</li>
<li>Scout the area: scenic routes, pullout areas, off the side of the road</li>
<li>Get off the beaten path. Don&#8217;t just come to a pullout area, get out, take a picture, and leave. Walk around a bit, get a different angle.</li>
<li>Things to consider for photographing: weather, clouds and light (arrive before a storm-clearing storm, fog create mystery, rain-saturated colors, snow-first dusting on mountains (versus white covered mountains), wind and movement</li>
<li>How to create perspective: lens coverage, distance to subject, and camera angle</li>
<li>The lens you choose is about the type of coverage you want</li>
<li>Focus using hyperfocal distance to get things near and far in focus.</li>
<li>Always use a tripod for maximum sharpness.</li>
<li>Camera angles: look down, look up, get low. Create depth with wide angle lens by getting up really close.</li>
<li>Use ND and Polarizers. Polarizers for foilage, water, and midst</li>
<li>User manual with spot metering on 18% grey of red or blue. Aim for exact exposure, not under or over. Shoot RAW and aim for f/16.</li>
<li>Foreground elements: fill the subject with the foreground element.</li>
</ul>
<p>One of Jennifer&#8217;s other favorite types of photography is star photography. Here are some great tips she offered for photographing stars:</p>
<ul>
<li>To avoid star trails and get points of light: Take 500 divided by focal length of the lens (if you are using a crop sensor, you have to take that into account and get the actual focal length) will give you the seconds to set your camera to get points of light. Anymore and you will have star trails</li>
<li>Use wide angle lenses at 30 seconds or less.</li>
<li>Shoot at wide open aperture (f/2.8, f/1.2 if you can)</li>
<li>For moonless night, set ISO to 3200, with moon (depending on how bright), set ISO to 200-400</li>
<li>Use your ISO to change exposure and not aperture or shutter</li>
<li>Turn your camera&#8217;s noise reduction on which is great help</li>
<li>After you take a night shot, let your CMOS sensor cool down for at least 30 seconds or you may have additional noise in your picture because of the heat on the sensor</li>
<li>Set your white balance to custom kelvin from 3200-3800 to give the nice bluish sky</li>
<li>WB custom 4200 works really well at the beginning of sunset, but not at 3 AM</li>
<li>Try focusing on the brightest star and not on a tree or foreground element. If nothing to focus on, set to infinity and back off a bit.</li>
</ul>
<h3>Conclusion</h3>
<p>This was a very informative free seminar sponsored by Canon. It was also an introduction course for those who signed up for the Canon Field Workshop the next day. Jennifer Wu has some absolutely stunning landscape shots and is able to articulate her technique and give steps and advice and not boring useless technical details.</p>
<p>As an added benefit, we were able to try all the twenty four lenses and four bodies and all the participants were given a free copy of the newly updated EF Lens Works III book that includes the new Canon Mark 3 bodies and new lenses. Awesome.</p>

		<description><![CDATA[A Nikon lens on a Canon body?! Is this an episode of the Twilight Zone?]]></description>
			<content:encoded><![CDATA[<p>When I first heard about the new <a href="http://www.bhphotovideo.com/c/product/520635-USA/Nikon_2163_AF_S_Zoom_Nikkor_14_24mm.html/BI/2448/KBID/3281">Nikkor AF-S 14-24mm f/2.8G ED N</a>, I was blown away at what a nice lens it must be. I have yet to see it or handle it in person, but from what I&#8217;ve seen in pictures, it&#8217;s one bad ass looking glass that I would love to have in my arsenal; especially more so after <a href="http://16-9.net/lens_tests/nikon_14_24mm_1/nikon14_24mm_a.html">seeing</a> <a href="http://www.kenrockwell.com/nikon/14-24mm.htm">the</a> <a href="http://www.fredmiranda.com/reviews/showproduct.php?product=336&amp;sort=7&amp;cat=28&amp;page=1">test</a> <a href="http://www.photozone.de/Reviews/46-nikon--nikkor-aps-c/361-nikkor-af-s-14-24mm-f28-g-ed-n-test-report--review">results</a>. The 14-24mm performs phenomenally in the lab and in the field. From what I&#8217;ve seen this Nikkor lens has to be the sharpest wide angle of this focal length even compared to similar focal range primes! The Nikkor 14-24mm blows away the <a href="http://www.bhphotovideo.com/c/product/486708-USA/Canon_1910B002AA_EF_16_35mm_f_2_8L_II.html/BI/2448/KBID/3281">Canon EF 16-35mm f/2.8L USM Mark II</a>, the <a href="http://www.bhphotovideo.com/c/product/519474-USA/Canon_2045B002_Super_Wide_Angle_EF.html/BI/2448/KBID/3281">Canon EF 14mm f/2.8L USM Mark II</a>, and let&#8217;s not even talk about Tamron, Sigma, or other third party manufactures. Between this lens and the <a href="http://www.bhphotovideo.com/c/product/518490-REG/Nikon_25434_D3_SLR_Digital_Camera.htmlhttp://www.bhphotovideo.com/c/product/519474-USA/Canon_2045B002_Super_Wide_Angle_EF.html/BI/2448/KBID/3281">Nikon D3</a>, I would switch back to Nikon if I had cash to burn. Actually it doesn&#8217;t make sense to switch brands just because the competitor has put out a better product. I&#8217;m confident in knowing that Canon will accept the challenge and give us Canon users a 1D that can actually auto focus with amazing low light capabilities that the D3 currently has. I&#8217;m not so concerned about the cameras, because to me, it&#8217;s the lens that makes the bigger difference. I rather invest my money in great quality glass than drop a wad on a camera that will be replaced a year later with something better for the same cost.<span id="more-433"></span></p>
<p><a rel="attachment wp-att-434" href="http://richbui.com/files/2008/04/1dm3-nikkor-14-24mm.jpg"><img class="alignright size-medium wp-image-434 hang-2-column" src="http://bui4ever.thebuicompany.com/files/2008/04/1dm3-nikkor-14-24mm-495x329.jpg" alt="" width="495" height="329" /></a>Then I read on <a href="http://www.16-9.net/lens_tests/nikon_14_24mm_1/nikon14_24mm_a.html">16-9.net</a>&#8216;s website:</p>
<blockquote><p>The other big news is that development is nearing completion of the Nikon G-Canon EF adaptor which allows this and any other Nikon G lens to be mounted on Canon DSLR bodies –with full aperture control.</p></blockquote>
<p>I also came across this site from the DPReview.com forums where this <a href="http://translate.google.com/translate?u=http%3A%2F%2Fwww.luciolepri.it%2Flc2%2Fmarcocavina%2Farticoli_fotografici%2FTEST_Canon_Nikon_full_frame%2F00_pag.htm&amp;langpair=it%7Cen&amp;hl=en&amp;ie=UTF-8">one guy mounted the Nikkor 14-24mm on a Canon EOS 5D</a> and did tests. Fortunately that means I don&#8217;t need to switch brands because by the beauty of technology, a converter, and heresy, I can use this lens on my Canon EOS 1D Mark II! Now why would I want to use a Nikon lens on a Canon body? Well for starters, it doesn&#8217;t really bother me that it is a Nikon lens. And Canon doesn&#8217;t offer a lens of this focal length. The closes is the Canon EF 16-35mm f/2.8L USM Mark II, which is <a href="http://www.16-9.net/lens_tests/nikon1424_17mm/nikon1424_17mm1.html">no where near as tack sharp</a> as this lens. Plus the 16-35mm is almost too much of an overlap for me. I already have the <a href="http://bui4ever.com/photography/canon_ef_24-70mm_f28l_usm">Canon EF 24-70mm f/2.8L USM</a>, I would be paying ~$1600 to use 8mm more of wideness. The Nikkor 14-24mm offers me 10mm more and having 14mm versus 16mm on the wide end can make a big difference in many cases. An easier way to analyze all this is to list the pros and cons:</p>
<h3>Pros</h3>
<ul>
<li>14mm and not a fisheye lens</li>
<li>f/2.8 aperture lens means it will perform very well in low light situations</li>
<li>Magnesium alloy body construction</li>
<li>Sharpest lens to date for the 14-24mm focal lengths even versus prime lens</li>
</ul>
<h3>Cons</h3>
<ul>
<li>Very expensive at ~$1700 and probably hard to acquire</li>
<li>Front element design is unable to take a screw on filter for additional protection</li>
<li>Lens hood offers nothing in the way of front element protection</li>
<li>Decent focal length</li>
<li>Need to spend additional money if trying to use this lens on a Canon body</li>
</ul>
<h3>Conclusion</h3>
<p>Is this lens worth it? I say yes, very much so. Canon does not offer a zoom lens as wide as this, it does however have a prime lens, the 14mm f/2.8L USM I &amp; II, that is the same focal length, <a href="http://www.16-9.net/lens_tests/canon14l2_nikon1424/nikon1424_canon14l2_a.html">BUT not the same sharpness</a>. For Canon shooters, the Canon EF 16-35mm f/2.8L had long been the photojournalist/wedding photojournalist lens, but I predict that as more and more Canon shooters see how great the Nikkor AF-S 14-24mm f/2.8G ED N lens is; this will be the new preferred lens leading to all sorts of shortages and back orders. Remember how long it took Nikon to meet production demands for the other hugely popular Nikkor lens, the 18-200mm f/3.5-5.6G?</p>
<p>I&#8217;m going to definitely start saving today and for awhile.</p>
<p><strong>[April 28, 2008 EDIT]</strong> In my haste of not reading very carefully, apparently using the Nikon 14-24mm f/2.8 with the 16-9 adapter mounted to a Canon SLR results in <strong>MANUAL FOCUS</strong> only. While this isn&#8217;t generally a big deal for people who photograph landscapes, having manual focus when you are trying to capture fast paced action makes it very difficult. So now I&#8217;m back to focusing on the Canon EF 16-35mm f/2.8L USM.</p>

			<content:encoded><![CDATA[<h3>Introduction</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/471581809/"><img src="http://farm1.static.flickr.com/207/471581809_44ab4ca8bf_m.jpg" alt="2006-09-17 - Canon 5D - 005" width="240" height="160" align="left" /></a>The Canon EOS 5D is pretty much about as professional of an digital SLR as you can get. It is one of the few full-frame sensor digital SLRs on the market. It feels very well built and handles like a charm. Plus a CMOS sensor of 12.8 megapixels definitely make for a lot of pixel details, so on paper it sounds quite promising, so how does it shape up in the field and in reality?</p>
<p>First, I must say I&#8217;m a bit biased against full-frame SLRs. I know there are a number of people who relish the fact that there are now a couple SLRs (both Canon) that are full-frame sensors similar to the ones found on film cameras. So what are the advantages of a full-frame sensor?</p>
<p><strong>Advantages </strong></p>
<ol>
<li>The focal length of the lens attached to a full-frame slr, such as the Canon EOS 5D, is precise versus the same lens being attached on a smaller sensor that results in a crop factor. So if I was to attach a 24mm focal length lens on a full-frame slr, it is precisely 24mm. But if I was to take that same 24mm focal length lens and attach it to, say an Canon EOS Rebel XTi/400D, the 24mm focal length becomes ~38.4mm because of the 1.6x crop factor.</li>
<li>Bigger sensor will resolve higher quality because there is more surface area to gather more light. And in relation to how closely or loosely packed the pixels are on a given sensor, there will be less noise on a full-frame slr versus a non full-frame slr given the same amount of megapixels.</li>
<li>Lower noise. This relates to #2, with a bigger sensor that can gather more light because of its larger surface area, less amplification is needed to boost signal thereby producing lower pixel noise.</li>
</ol>
<p><strong>Disadvantages</strong></p>
<ol>
<li>Cost is considerably higher. More raw materials are needed to produce a larger sensor and a larger body is necessary to house a larger sensor.</li>
<li>The weaknesses in cheaper and poorly produced lenses are much more apparent and blaring.</li>
<li>Similar issues with the full-frame film sensors: vignetting and softness in the corners.</li>
</ol>
<p>So what are my thoughts after <a href="http://bui4ever.com/blog/2007/07/16/canon_eos_5d.php#respond">using the Canon EOS 5D for two weeks</a> so far (which I must warn is no where near enough time to get an accurate feel)?</p>
<h3>Weight and Dimension</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/471563090/"><img src="http://farm1.static.flickr.com/229/471563090_114d3e43f7_m.jpg" alt="2006-09-17 - Canon 5D - 007" width="240" height="160" align="right" /></a>The Canon EOS 5D is definitely not a light digital SLR. It weighs 810g (892g with the battery), which is about 1.78 pounds. It is quite large in your hands, not quite as large as the Canon EOS 1D line, but definitely bigger than the Canon EOS 20D/30D and hugely bigger than the Canon EOS Digital Rebel line. The exact dimensions are 6.0 x 4.4 x 3.0 inches. Because of the huge grip, it is comfortable to hold and use.</p>
<h3>Construction</h3>
<p>Much like its younger brothers, the Canon EOS 20D/30D, the entire body is made up of magnesium alloy right down to the EF mount. It is not weather sealed, unlike its bigger brother, the 1D line.</p>
<p>In the tradition of professional level SLR, there is no built on pop-up flash (partly due to the huge viewfinder), so an external flash unit would have to be used. The buttons are slightly different than the Canon EOS 20D/30D. The four buttons (Menu, Info, Jump, and Preview) that are left of the 2.5&#8243; LCD is slightly raised higher than on the Canon EOS 30D. The On/Off switch is also more pronounced. The two buttons on the back upper right hand side is also different than the 30D. The Auto Exposure Lock/Zoom Out button is larger than the Zoom in button whereas on the 30D, it is the reverse being that the Auto Exposure Lock/Zoom Out button is larger and the other is smaller. And the final major difference is the jog dial doesn&#8217;t have the Picture Style selection that the 30D has.</p>
<h3>Field Test</h3>
<p>It&#8217;s definitely wild to be able to have a wide angle lens really be a wide angle lens. My walk around lens, the Canon EF 24-70mm f/2.8L USM is amazingly wide allowing me to capture more than I was able to capture before. The catch-22 to having no a full-frame sensor is that while my lenses are all now wider like it should be, I don&#8217;t have the same focal crop I had before. At times I am finding the 70mm focal length on my walk around lens to be lacking that extra little field of view I used to have with my Canon EOS Digital Rebel XTi/400D. I find myself switching lenses back and forth more often with my Canon EF 70-200mm f/2.8L USM.</p>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/471581957/"><img src="http://farm1.static.flickr.com/202/471581957_ee45563279_m.jpg" alt="2006-09-17 - Canon 5D - 001" width="240" height="160" align="left" /></a>I also do find that both my lenses are better counter-balanced on the Canon EOS 5D because of its weight than when the two lenses were mounted on my XTi. I don&#8217;t find my trigger finger and hand to be as sore because I&#8217;m not having to support all the lens weight through the smaller grip. I do find myself garnering more attention these days because everything looks so big now. Before the lens was intimidating for people, but with the 5D now, everyone is just surprised by the sheer size.</p>
<p>Having the extra megapixelage is quite nice. It allows for some amazing crops that I could never have achieved with my Nikon D100. While the Canon EOS 5D only has a 2.8 megapixel advantage over the Canon EOS Digital Rebel XTi/400D, the differences in the pictures is quite evident. This also further proves that megapixels do not mean everything. I would have personally preferred a faster  burst rate (3 frames-per-second), but it has the highest buffer of all the other Canon dSLRs, except for the Canon 1D Mark III, with 60 JPEGs. The XTi could only manage 27 JPEGs at best before slowing down to 1 frame-per-second. The 3fps is quite adequate for most and many occasions, but having an additional 2fps would be great for sports photography.</p>
<p>The ISO noise suppression on the 5D is amazing. When I have to use ISO 800, there is less noise in the pictures than my Canon EOS Rebel XTi/400D at the same ISO level. ISO 800 on the Canon EOS 5D looks equivalent to the XTi/400D&#8217;s ISO 400.</p>
<h3>Final Thoughts</h3>
<p>The Canon EOS 5D is very, very nice, but I wouldn&#8217;t buy it. It is three times as much as my XTi/400D and double the price of the Canon EOS 30D, but doesn&#8217;t offer enough over the 30D and the XTi/400D to be worth it. But then again the 5D is a very specific niche dslr. It has a full-frame CMOS sensor at about a third the cost of the Canon EOS 1Ds Mark II with a few less megapixels also. I would rather spend the extra $200 and purchase the Canon EOS 1D Mark IIn or Mark III over the 5D. But if you need full-frame and top notch ISO noise control, then the Canon EOS 5D is your choice. Full-frame is nice, especially when you need wide angle, but I personally need more reach than I need wide and the 1.3x crop factor of the 1D is a good compromise between full-frame and 1.6x crop factor.</p>

			<content:encoded><![CDATA[<h3>Specification</h3>
<p>Canon EF 28-135mm f/3.5-5.6 IS USM on Canon EOS Rebel XTi/400D.</p>
<p>[TABLE=8]</p>
<h3>Introduction</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/468633697/"><img src="http://farm1.static.flickr.com/186/468633697_da981f2cb4_m.jpg" alt="2007-02-11 - Stripes Bui - 006" width="160" height="240" align="left" /></a>This is the lens that my dad purchased to use with his Canon EOS 5D. This lens definitely wouldn&#8217;t be my first choice if I had a 5D, it&#8217;s kind of like buying a Ferrari but filling up with 87 unleaded, but to each his own I guess. <a href="http://bui4ever.com/blog/2007/02/04/traded-lens-with-my-dad.php/">My dad and I traded lens</a> for a while back (just to try), my Canon EF 24-70mm f/2.8L USM for his Canon EF 28-135mm f/3.5-5.6 IS USM.</p>
<p>I didn&#8217;t use the lens as often as I would have liked to, a combination of bad weather days and being busy, but I used it enough to get a general idea of the lens.</p>
<h3>Weight and Dimensions</h3>
<p>Well compared to the Canon L series lens, this lens feels like nothing. At about 540g, it is almost half the weight of the Canon EF 24-70mm f/2.8L USM&#8217;s 950g. It is also smaller, coming in at 78.4mm x 96.8mm. Very easy to carry my Canon EOS Rebel XTi around with this lens attached.</p>
<h3>Construction</h3>
<p>This lens is made of nothing but plastic. The only metal on the entire lens are the screws and the lens mount. There is some noticeable &#8220;wiggle&#8221; when the barrel is extended to its full length of 135mm. Turning the zoom room feels ok, not very smooth though. The focus ring is the same.</p>
<p>Unlike the L series lenses, you definitely do not want to drop it at all.</p>
<h3>Field Test</h3>
<p>The focal range on this lens is excellent! 28mm to 135mm is very nice to have in one lens. I did find starting at 28mm is definitely not wide enough for me, especially on a 1.6 frame of view crop factor, turning this<a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/468624996/"><img src="http://farm1.static.flickr.com/232/468624996_e5cbf589a6_m.jpg" alt="2007-02-11 - Stripes Bui - 026" width="160" height="240" align="right" /></a> 28mm to 44.8mm. But on the other hand, having a lens that is versatile such as this is great, especially when you have no idea what kind of reach you need to get a shot.</p>
<p>The IS is a great feature to have, as with all the other lenses that have IS also. This lens needs it a bit more so because of it&#8217;s maximum aperture of 3.5. IS does drain the battery, so use it when necessary if you need to conserve battery juice.</p>
<p>Because its a small and light lens, but covers an expansive focal range, I find this lens is perfect for hiking or just walking around. This lens performs quite poor in low light because of its maximum aperture. You&#8217;ll have to dial up the ISO.</p>
<p>Worth mentioning is that there is some noticeable barrel distortion at 28mm which becomes pincushion after 45mm.</p>
<p>Getting nice bokeh from this lens is difficult for two reasons, f/3.5 and a 6 blade aperture. Easiest way to accomplish it is to stand close to the subject but using a long focal length.</p>
<h3>Final Thoughts</h3>
<p>This is actually a pretty good lens for the features versus price. You&#8217;re getting a great range, 28mm-135mm, ring type USM, limited macro <strong>and</strong> IS all for under $500. It&#8217;s actually quite amazing that Canon decided to include not only IS but ring type USM that is generally found on the more pricey lens such as the L series. For those that don&#8217;t know, ring type USM is the super fast and quiet focusing system that Canon utilizes that allows for Full-Time Manual (FTM) without having to toggle a switch. Nikon&#8217;s equivalent to this is AF-S.</p>
<p>This lens also has limited macro capabilities like the Canon EF 24-70mm f/2.8L USM, which is great for people who take macro shots occasionally but not enough to spend money on a true macro lens.</p>
<p>The build quality isn&#8217;t so great, but perhaps I&#8217;m biased and the optically quality is decent. This is a very popular lens with many users from beginners to pros alike, can&#8217;t go wrong with it.</p>
<p>A great lens for those on a budget and also a great backup lens.</p>

			<content:encoded><![CDATA[<h3>Introduction</h3>
<p>It took a bit of agonizing trying to decide what would be the replacement SLR to my Nikon D100. I knew for sure that I was <a href="http://bui4ever.com/blog/2007/01/08/the-switch-from-nikon-to-canon.php/">making the switch to Canon</a>. Ironically <a href="http://bui4ever.com/blog/2006/08/24/canon-eos-400ddigital-rebel-xti.php/">my friend saw it coming</a> before I even realized it. It had just come time to upgrade.</p>
<p>So at first I was not even considering the Canon EOS Rebel XTi/400D because I felt it was too &#8220;entry level&#8221; SLR for me, so I was considering a used Canon EOS 20D instead. I really wanted the Canon EOS 30D because of the improvements over the 20D, but the cost of the SLR alone would make it difficult for me to have any quality lenses. I was considering a used Canon EOS 30D at one point, but figured it might be too dangerous of an investment considering buying used electronics, too unpredictable when it may just decide to crap out especially without a warranty. So I was considering a Canon EOS 20D again because of its price and it still had many of the features I wanted despite a new model being out. After number crunching, I decided perhaps the Canon EOS Rebel XTi might be a good idea after all.</p>
<p>For the cost vs. what it offers, you can&#8217;t really beat the price. I got mine brand new from a Canon authorized dealer, <a href="http://www.beachcamera.com">Beachcamera.com</a>, body only, for under $700 dollars.</p>
<h3>Weight and Dimensions</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/353012962/"><img src="http://farm1.static.flickr.com/164/353012962_a759e630b7_m.jpg" alt="2007-01-08 - Canon EOS Rebel XTi - 009" width="240" height="160" align="left" /></a>They weren&#8217;t kidding when they said this SLR was small. It&#8217;s practically the size of a larger point-and-shoot, in fact it probably could be confused for a point-and-shoot if not for larger lenses attached. My finger tips feel practically smashed against the lens mount, that&#8217;s how tiny it is. At first it was quite uncomfortable to use, especially since I was using a Nikon D100 before, but after you get used to it, its not so bad. I&#8217;ve used my friend&#8217;s Canon EOS 30D and my Dad&#8217;s Canon EOS 5D, and when you have been using the XTi for awhile, holding the other two bigger SLRs feels completely different.</p>
<p>The XTi is very light, almost feels like there is nothing inside. The lightness can be both a good and bad thing. It&#8217;s good because you&#8217;re carrying less, but it&#8217;s bad when you have a big lens attached such as the Canon EF 70-200mm f/2.8L USM. Without the top LCD, Canon has achieved a SLR the size of mid-sized point-and-shoots, which makes being stealthy easier.</p>
<p>Lighter lens mounted to the XTi is no issue, but when you mount an L lens, it becomes very front heavy. Everything time I have my 70-200mm f/2.8L mounted, I&#8217;m bracing the lens rather than the camera.</p>
<h3>Construction</h3>
<p>The XTi is primarily constructed of polycarbonate with magnesium around the lens mount and CMOS sensor. It definitely feels plastic, but don&#8217;t let that detract you from how great this camera really is. It definitely is very well constructed and put together despite being plastic. I have my Canon EF 24-70mm f/2.8L USM attached to it primarily, and the Canon EF 70-200mm f/2.8L USM for special events, and it doesn&#8217;t feel like the lens mount is going to break off. Take it from a guy, who at times, carries his camera with the 24-70mm or 70-200mm attached via the neck strap slinged on one shoulder walking around. I know some people would cringe at the thought&#8230;</p>
<p>I know many people and many sites have commented on how much more comfortable the Nikon D80 and even the Nikon D40 (despite being smaller than the XTi) is. I have held both for a bit and agree that the two Nikons are definitely more comfortable.</p>
<h3>Field Test</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474238670/"><img src="http://farm1.static.flickr.com/200/474238670_6eb04355c9_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 005" width="240" height="160" align="right" /></a>Because this is my primary (only, currently) body, I use it whenever I need to take pictures. It gets a lot of use and while I don&#8217;t baby it, I don&#8217;t abuse it either. The body still looks relatively new other than for a few cosmetic blemishes such as my fingertips digging into the rubber inserts to hold the camera.</p>
<p>I always get looks when I pull out my XTi because I have two main lens, the 24-70mm and the 70-200mm both f/2.8 which means <strong>big</strong> lenses, and the 24-70mm is usually what I have mounted. It looks a bit comical at first, such a small camera but such a big lens.</p>
<p>The small size of the XTi makes traveling with it very easy. I can easily stow it away in my car and carry it with me to snap nice high quality shots. My lenses do kind of negate the smallness benefit of the XTi though&#8230;</p>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474263299/"><img src="http://farm1.static.flickr.com/178/474263299_07c2aebcf3_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 031" width="160" height="240" align="left" /></a>The 2.5 inch LCD screen is great, I love it, especially since I went from a 1.8 inch LCD screen on the Nikon D100. One major thing I highly recommend doing to protect your LCD is purchasing the <a href="http://www.amazon.com/Palm-Premium-Protectors-Multi-pack-3177WW/dp/B00062GJ8E">Palm Premium screen protectors multipack</a> and applying it to your LCD. You will have to do a bit of measuring and cutting, and it may take a few times before you get it perfect, but it is all worth it. It doesn&#8217;t affect the color or view angle of the LCD in any way. Worthy investment.</p>
<p>In the beginning, I figured the dust sensor cleaning feature was a gimmick by Canon, but after a bit of comparison with my friend&#8217;s 30D, it does in fact work. I change my lenses much more often than my friend does (he only has one lens&#8230;at the moment&#8230;), but I have hardly any sensor dust compared to him and he is much, much more careful about how he changes his lenses to prevent dust such as facing the camera downwards to avoid introducing new dust artifacts on the sensor, me, I just plop it off and on.</p>
<p>The battery life is actually quite good. I don&#8217;t have an exact count of how many shots you can take before you have to recharge the battery, but I find that I rarely have to recharge the battery. When the battery is depleted, it doesn&#8217;t take long to recharge the battery back to full either, some three hours I believe. And in no accident, the Canon NB-2LH battery is compatible with the XT, Canon PowerShot S30/40/45/50/60/70/80, and the Canon G7.</p>
<h3>Final Thoughts</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474259183/"><img src="http://farm1.static.flickr.com/200/474259183_8cbbbde80d_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 010" width="240" height="160" align="right" /></a>While I am definitely overall very happy with the SLR, there are a few points that do irritate me. First and foremost, the limited ISO steps. My ISO choices are: 100, 200, 400, 800, 1600. The jump from 400 to 800 is ridiculous! Sometimes I need 600 or around 600 and 800 is a bit overkill. The XTi does do very well in noise suppression, but going from 400 to 800 is a bit much in my opinion. I would definitely like to be able to adjust my ISO in 1/3 steps versus full steps, but I guess this is where entry-level comes into play.</p>
<p>There is no easy way to change the focus point. On the Canon EOS 30D and Canon EOS 5D, there is a little independent mini joystick that you can set to be a dedicated focus point changer. On the Rebel XTi, I have to press the focus point button, then use either the four point cursor keys or the jog wheel near the shutter. This results in missed shots because of having to press the button and then search for where I want the focus point set.</p>
<p>I&#8217;m not a big fan of the limited buffer. While the frames per second (3 FPS) is decent, the buffer of 27 high quality JPEGs feels limiting, although there is very few reasons to deplete the buffer. But somehow Nikon&#8217;s D40 and D80&#8242;s 100 picture buffer seems much more appealing.</p>
<p>If the Canon XTi&#8217;s body was made of all magnesium alloy, I think it would be perfect, although it probably would cost almost as much as the Canon EOS 30D.</p>
<p>Also having 10.1 MP is nice, makes having to do drastic crop downs still look pretty damn good.</p>
<p>This camera is definitely worth having as your primary and/or secondary camera. It has many features of the Canon 30D, but at nearly half the price. Eventually I would love to have the Canon EOS 1D Mark IIn or even the newly released Canon EOS 1D Mark III, I probably would still use the XTi a lot. It&#8217;s small, portable, cheap, and can use all the lenses so it makes a perfect backup camera or a traveling camera.</p>

[table=7] Introduction There are many reasons as to why you would find this lens in virtually everyone&#8217;s bag, it&#8217;s probably Canon&#8217;s best lens for its focal range, build quality, and sharpness.

			<content:encoded><![CDATA[<h3>Lens Review</h3>
<p><a href="http://www.flickr.com/photos/bui4ever/sets/72157600137595112/">Canon EF 70-200mm f/2.8L USM</a> on Canon EOS Rebel 400D/XTi.<br />
[table=7]</p>
<h3>Introduction</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474246294/"><img src="http://farm1.static.flickr.com/220/474246294_4f40d116d0_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 011" width="240" height="160" align="left" /></a>There are many reasons as to why you would find this lens in virtually everyone&#8217;s bag, it&#8217;s probably Canon&#8217;s best lens for its focal range, build quality, and sharpness. This lens easily becomes anyones favorite after one or two uses. It&#8217;s solidly built and very well constructed.</p>
<p>With a 1.6 frame of view (FOV) crop, the 70-200mm becomes a 112-320mm, quite a usable range. Whereas my <a href="http://www.bui4ever.com/photography/canon_ef_24-70mm_f28l_usm/">Canon EF 24-70mm f/2.8L USM</a> is my carry around lens, I find myself using the Canon EF 70-200mm f/2.8L USM for outdoor and indoor events such as the <a href="http://www.flickr.com/photos/bui4ever/sets/72157600111900345/">Cherry Blossom Festival</a> and the <a href="http://www.flickr.com/photos/bui4ever/sets/72157600059281856/">Grand National Rodeo</a>.</p>
<h3>Weight and Dimension</h3>
<p>This is definitely not a small lens by any means, its dimensions are 3.3&#8243; x 7.6&#8243; at a smudge under 3 lbs making it heavier than the Canon EF 24-70mm f/2.8L USM. With the 70-200mm attached on small SLRs such as the Rebel line, you find it is noticeably nose heavy. It doesn&#8217;t start getting balanced out until you attach it to a Canon EOS 1D line, but by that point, you&#8217;re holding onto more than 6 lbs!</p>
<p>As with almost all the other Canon L lenses, the filter size is the 77mm. I&#8217;m currently using a B+W 77mm MRC (010) UV Filter which <a href="http://www.the-digital-picture.com/Reviews/B+W-UV-Filter.aspx">The-Digital-Picture.com exclusively uses</a>. Originally I was going to go with a Hoya Super HMC Pro, but kept hearing so much about B+W filters that I figured why not. If I was going to buy a Ferrari, I wouldn&#8217;t fill it up 87 gas.</p>
<h3>Construction</h3>
<p>Built like a tank, just like the other Canon L lenses. Every piece is so meticulously constructed, you could use this lens thousands of times and it would still look new. Even if you <a href="http://www.kenrockwell.com/canon/lenses/70-200mm-f28-is.htm">dropped it from on top of an elephant</a>, it still works great! Also worth mentioning, the non-IS version <strong>is not</strong> weather sealed. Of the four Canon EF 70-200mm (f/2.8L, f/4, f/2.8L IS, f/4L IS), only the image stabilizer (IS) versions are weather sealed.</p>
<p>There is really not much more to mention about its construction that hasn&#8217;t already been said by many people already.</p>
<h3>Field Test</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474257171/"><img src="http://farm1.static.flickr.com/197/474257171_50f78211f6_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 014" width="160" height="240" align="right" /></a>For day-to-day shooting, I rely upon my Canon EF 24-70mm f/2.8L because of its semi-wide angle and allows me to get close up to subjects and objects and its limited macro capabilities. For events such as concerts, festivals, and what not, the Canon EF 70-200mm f/2.8L becomes the lens I use for many reasons, but usually because I need the extra reach.</p>
<p>The picture quality is superb on many levels. The colors are vibrant and jump out at you and the sharpness is next to none. This lens is definitely sharper than my Canon EF 24-70mm f/2.8L and has slightly better colors, contrast, and saturation using all the same camera settings. Very little post processing is needed when using this lens.</p>
<p>The bokeh achieved by this lens is nothing less than fantastic. The background is always nicely blurred out when using f/2.8 or a long focal range (100mm+) on a nearby subject. It is definitely not difficult to get great looking bokeh with this lens.</p>
<p>The AF on this lens is lightening fast and focuses accurately on subjects and objects. I rarely ever have cases where the 70-200mm is &#8220;hunting&#8221; for focus. Precision is very important, especially when shooting sports, which makes this lens a great lens for fast moving subjects or objects.</p>
<h3>Overall Thoughts</h3>
<p>There is only one reason I would part with this lens, to get the Canon EF 70-200mm f/2.8L <strong>IS</strong> USM. While the difference in the price is quite a bit, <strong>it is very much worth it</strong> to get the IS version. This lens also attracts a lot of attention, being the trademarked &#8220;white&#8221; L lens and its size (especially with the pedal hood on).</p>
<p>The lens comes with a very nice canvas carry case, pedal hood, and most of all, a tripod mount which  the Canon EF 70-200mm f/4L versions do not come with.</p>
<p>Check out these shots (<a href="http://www.flickr.com/photos/bui4ever/sets/72157600111900345/">Cherry Blossom Festival</a> and <a href="http://farm1.static.flickr.com/216/452580311_484a950a83_s.jpg">Grand National Rodeo</a>), all made with the Canon EF 70-200mm f/2.8L USM and make your own decision if it&#8217;s worth it or not, in my opinion, it is worth every penny.</p>

			<content:encoded><![CDATA[<h3>Specifications</h3>
<p><a href="http://www.flickr.com/photos/bui4ever/sets/72157600137422137/">Canon EF 24-70mm f/2.8<span class="red">L</span> USM</a> on Canon EOS Rebel 400D/XTi.</p>
<p>[table=6]</p>
<h3>Introduction</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474239968/"><img src="http://farm1.static.flickr.com/173/474239968_e53ad8ea45_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 001" width="240" height="160" align="left" /></a>From the first time I heard about the Canon EF 24-70mm f/2.8<span class="red">L</span> USM lens, I had a feeling it would be a lens I would really like. I was wrong. I am absolutely in love with this lens. It is amazing! From the feel to the picture quality, superb. There are few people who say this lens is way too overrated. Some aren&#8217;t as impressed as others and claim that the Tamron 28-75mm f/2.8 performs just as well for a lot less in price and is smaller, more compact and supposedly the Sigma AF 24-70mm f/2.8 DG DF performs about as good as the Canon EF 24-70mm f/2.8<span class="red">L</span> and better than the Tamron. I personally have not used the Tamron or the Sigma and can&#8217;t comment.</p>
<p>This lens is my walk around lens. It may seem a bit *big* at first to be a walk around lens on a Canon EOS Rebel 400D/XTi (hell, it&#8217;s still not even considered small on the Canon EOS 20D or Canon EOS 30D), but you get used to it quite quickly especially after seeing the the sharpness and performance of the Canon EF 24-70mm f/2.8<span class="red">L</span></p>
<p>The focal length of this lens on a 1.6 FOVCF (frame of view crop factor) SLR such as the Canon EOS Rebel 400D/XTi is 38.4mm to 112mm, somewhat odd range, but still usuable.</p>
<h3>Weight and Dimensions</h3>
<p>This len isn&#8217;t small. It&#8217;s a bit longer than the Canon EF 17-55mm f/2.8 IS and is only a bit shorter than the Canon EF 70-200mm f/4<span class="red">L</span>. It weighs 950 grams (or 2.1 pounds), so it&#8217;s heavier than the Canon EF 70-200mm f/4<span class="red">L</span>, but not as heavy as the Canon EF 70-200mm f/2.8<span class="red">L</span>. The actual dimensions are: 4.9 inches length-wise and 3.3 inches in diameter. It has 13 groups and 16 elements; definitely a lot of glass in this lens! With this lens attached to the Canon EOS Rebel 400D/XTi, I find myself sometimes holding the camera/lens by the lens body rather the grip because it feels a bit more comfortable and I&#8217;m not as afraid of dropping this $1,000 lens. I see many people complain about the weight of this lens. It&#8217;s not light, but certainly not heavy like Canon&#8217;s super telephoto lens, the 500mm and 600mm. Those that complain of the weight don&#8217;t seem to appreciate the superior build quality and the picture quality achieved by this fantastic lens.</p>
<h3>Construction</h3>
<p><a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474251559/"><img src="http://farm1.static.flickr.com/167/474251559_921b7757c3_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 002" width="240" height="160" align="right" /></a>Because this is an <span class="red">L</span> lens, it is primarily constructed of magnesium alloy and most certainly feels like it can take a pounding and continue taking great pictures. The barrel that extends is also constructed of magnesium alloy and you can feel how well its built when the barrel is fully extended out. There is virtually no significant wobbling of any kind with the lens when the barrel is collapsed or fully extended. This <span class="red">L</span> lens is black in color, unlike it&#8217;s bigger brothers, who are painted in the now famous Canon color, off white (or putty). Because of that, it may not garner glances as quickly as a white <span class="red">L</span> lens usually does, people still notice that it is not a small lens either. When you attach the flower hood (EW-83F), it really stands out.</p>
<p>The focal length ring rotates smoothly and tightly allowing for precise adjustments. It feels great when you spin either the focal length ring or the focus ring. This is definitely an excellent engineered lens. One thing that many people may find a bit odd at first is how the focal lengths work. When the barrel is fully collapsed, it is at its fartherest focal length, 70mm. To use 24mm, the barrel is focused out. I believe part of the reason that Canon designed the lens this way was because of the huge hood. The hood attaches to the body and not the barrel like some other lenses does (for example, the Nikon AF 28-200mm f/3.5-5.6G ED-IF) and if 24mm was when the barrel was completely collapsed, parts of the hood would appear in the shot. One added bonus is that with the hood on and the barrel fully extended, the barrel remains inside of the hood still, which is great protection in the unlikely event you drop the lens.</p>
<h3>Field Test</h3>
<p>I usually have the Canon EF 24-70mm f/2.8<span class="red">L</span> USM attached to my camera; as it is my walk around lens. There are a few times that I feel a bit limited by 70mm and want to be able to zoom more and other times I feel that 24mm isn&#8217;t wide enough.</p>
<p>The maximum aperture of 2.8 allows me to get shots in dimly lit areas, which is a great bonus. This is definitely not a lens I would use for shooting sports because of its limited focal range, but using it for portraits is very satisfying. It creates a very smooth and buttery blurred background (bokeh) at 2.8.</p>
<p>Auto focus is extremely fast on the Canon EF 24-70mm f/2.8<span class="red">L</span> because of ring type USM. It also<a title="Photo Sharing" href="http://www.flickr.com/photos/bui4ever/474250311/"><img src="http://farm1.static.flickr.com/212/474250311_c2b9c052ff_m.jpg" alt="2007-04-26 - Canon Photo Equipment - 007" width="160" height="240" align="left" /></a> focuses accurately and does well under low light conditions.</p>
<p>I&#8217;m unable to use my built on flash with this lens attached because it will cause very noticable lens vignetting on the bottom center of the pictures. It doesn&#8217;t bother me too bad because I try to avoid using flash as much as possible.</p>
<p>Another great thing about this lens is the macro feature. It can focus as close as 1.25 feet, much better than my Canon EF 70-200mm f/4<span class="red">L</span>&#8216;s 3 something feet. While this isn&#8217;t quite super impressive, it&#8217;s very usable for me. There are times I like to take macro images, such as product images and what not, so I need a good macro lens, which I previously was using the cheapy kit lens, Canon EF-S 18-55mm f/3.5-5.6.</p>
<p>It&#8217;s a great lens with decent focal range. Good enough to spend 85% of the time on my SLR body. The weight isn&#8217;t too big of an issue, you get used to it, especially when you see the image quality.</p>
<h3>Overall Thoughts</h3>
<p>This lens would be perfect if it had Image Stabilizer (IS) on it. There are just some times in some dimly lit areas (such as indoors) where IS would help quite a bit! I highly recommend this lens.</p>
