Rob Galbraith DPI: Canon announces 17.92 million image pixel, 8fps EOS 7D
"Canon appears to have done a masterful job of wringing out every ounce of quality from the 7D's little pixels (smaller than any Canon before), resulting in photos that are fairly crisp, reasonably clean and usable up to about ISO 1600."
"Noise, when it appears, has a natural graininess to it, up until about ISO 1600 as well. At ISO 3200 and beyond you'll run into increasingly unmanageable amounts of digital dandruff (white pixels spread throughout darker areas) and plugged shadows. At all ISO increments, other than the very lowest ones, pictures can take on a somewhat harsh, chunky appearance not present in larger-pixel cameras in Canon's lineup, such as the EOS-1D Mark III. Or Nikon's D3 and D700.
Correcting for digital dandruff requires image detail to be softened, sometimes considerably, while the slight harshness is simply a trait to be lived with."
"This means that overall, 7D image quality is shaping up to be decent, though not groundbreaking. If you're coming from a 50D or Rebel T1i, you're likely to be right at home with the picture quality from this camera. If you're coming from a camera like the 5D Mark II, the 7D's pictures will almost certainly seem inferior, in some instances by a fair margin."
It's interesting that, now that Buckster owns a 5D Mark II and a 7D, that he can see the image quality differences between the 7D and the 5D-II. So can other impartial observers. the 7D has a nice list of body features, but it does not deserve to be defended like your sister's virginity, to quote a certain someone involved in this post.
The 7D's image quality is good, but not outstanding. the 7D has less-saturated color than other Canon cameras, it tends to create plugged shadows, and it suffers from higher than expected noise beginning at ISO 400. It has the tiniest pixels ever incorporated into a Canon d-slr camera. The increase in megapixels that Canon decided upon for the 7D sensor ended up costing color richness, clean shadows, and low noise; there is NO FREE LUNCH, and there is no escaping the principles of physics.
As Rob Galbraith said, "If you're coming from a camera like the 5D Mark II, the 7D's pictures will almost certainly seem inferior, in some instances by a fair margin." I find it interesting that Buckster, now that he owns a 5D-II, can easily see, and admit, that the image quality of the 7D is not the same as that of the 5D-II. And yet, there are two or three people on this board that CONSTANTLY defend the 7D, and CONSTANTLY try and belittle, defame, and insult anybody who dares to bring up **any** shortcomings their beloved 7D might have. Fanboys.
