Summary: I came from the EOS 40D which is a GREAT camera, but I have to say the 5D is amazing. Even at ISO 1000 or long exposures there is very little if any noise in my photos. I didn't realize how nice having a full-frame sensor would be, and am loving the true wide-angles I can get now.
Summary: The Canon 5D is still one of the best cameras available. The full frame sensor captures very high quality images. And a 12 mega pixel image is more than enough unless you are making wall size murals.
Pros: Comfortable Controls, Image quality, Strong Construction
Summary: It was hard (and expensive) to go from Nikon to Canon, but worth it. I always felt my Nikon could be sharper. I went to Canon for the Lenses and I'm not disappointed, nor will you be. The D5 with the 24-105 L series lens is a beautiful setup, extremely versatile. This is not a compromise camera.
Summary: The 5D is the quintessential Canon SLR, offering a smart, functional mix of essential features and technologies – and little more. The reason to get this camera are its compact size, large bright viewfinder and full frame sensor, which make it the only game in town for folks need all these...
Pros: Compact Size, Crisp detailed images, Full Frame Sensor, Large bright viewfinder, Quiet
Cons: CF door feels cheap, Minimal viewfinder info, Quality control not great
Summary: As a wedding photographer I love the Canon 20D, nice and light and at a good price I can afford six of them. But, recently I started shooting for a local magazine and felt I needed a better camera. The full frame feature is the number one reason for this purchase.
Summary: This camera is a dream to work with in almost every way imaginable! The pictures are consistently amazing and true to what I intended to shoot; right down to exposure, color, etc. A feat seemingly more and more difficult on some of the newer canon models (XTi for one).
Summary: I don't usually write reviews but I was fortunate enough to be in a position to purchase this camera as soon as it's available and their aren't that many user reviews out yet so I'll add mine: This camera is a fantastic pro machine.
Conclusion: I find the official review on this web site suffers from the reviewer's personal bias (or animus), and fear it lacks objectivity.Two years after it's release, the 5D is the lowest cost full frame DSLR available - much lower than the prospective price of the recently announced D3.
