This test is very timely for me, as I have just received my copy of this lens, and I am about to leave on a trip that will include photographing wildlife. I am lucky enough to own both a 7D and a 5D III. I assumed I would bring the 7D to use with this lens, but the tests seem to show that would be the wrong choice.
For this question, assume the lens is at 600mm and f8, and the subject would nicely fill the frame (no additional cropping in post) on the 7D. Do these tests show that if I used the 5D III instead, and then cropped the image to be the same size as from the 7D, that the 5D III image would have more resolution and better detail?
