On page 2 there is a noise test.


It always seems that body comparison threads start the same way. A Page of general comparisons then it isinevitable, it turns in to several pages of technical discussion on Noise.


One of the things I did not like about the 7D using it with the 500mm, it seemed I was always fighting for light. What I mean by this, I didn't like getting the ISO to high. Often wildlife shots are in less than ideal lighting situations. So I found myself shooting slower shutter speeds to keep the ISO down, then the shutter speed would be to slow. With the shutter speed slow, say at 1/500 it gets really hard to "hand hold" the lens even with IS and get a good sharp picture. That said this is one of the things I really like about the 1D IV, it doesn't feel like I am fighting for shutter speed as much. It makes the 1.6 vs 1.3 crop factor loss a forgotten issue.


The 7D just doesn't handle the higher ISO's as well as the 5D II or the 1D IV. I still stick by my conspiracy theory(which is...the 7D is dumbed down somewhat with the firm ware). Part may or may not be the sensor depending on who's opinion you read.
