Who really cares about the math involved re FOV and crop reach? The 7D simply gives you a better image than the 5DII image cropped to result in the same-sized final image.
For my practical purposes, my 1DMk4 makes my 400mm a 520mm. To hell with the math.
Exactly!
Practical means this: I have a 5D2, 1D4, and 7D and some telephoto lens... A critter approaches. Which body do you grab if your goal is to fill the frame with said critter?
The answer depends on a few things such as the size of the critter, how fast he moves, what my goal is for the image, etc.... No math needed to make this decision. All 3 cameras can produce an excellent image.. the goal is the least amount of cropping possible.
Generally, I carry my 7D with a 400 5.6 and my 5D2 with a 70-300 4-5.6L. This is my \"generic\" wildlife setup. Sometimes, I switch this around if I want to do BIF with the 70-300 and then use the 400 for larger, perching critters. In the bag I may have a 16-35, 24-105, 70-200 -- depending on conditions, etc....
I have a 1D4 on loan from CPS that I\'m evaluating against the 7D.... One of the worries is the 1.3 VS 1.6 crop. I expect the 1D4 will be better in every other way.
