I have just got my 7D in yesterday and I am going to do some very deep testing with the equipment I have on both cameras to see how, if at all, the 7D is or isn't worth the leap from the 40D. I am also looking for input on anyone out there with similar equipment and may have IQ comparison questions.
My personal test will include the obvious, all lenses I own on both camera, focusing, ISO, resolution comparison, downsizing IQ, sharpness with the lens correction ability of the 7D, 100% crops, over all IQ.
It will be a very controlled and documented test. If anyone has a test suggestion or an idea they would like to have seen threw on this comparison please list it below.
Thanks, I will post back in a day or two and I will check for posted test ideas.
