I thought the 7D had good AF, but the 1DMKIV is on another level. The AF with the 500mm f4L is slow due to the motor in the lens, not the camera. The motor needs to move a lot of glass, I guess, but I have a feeling a Nikon D300s + 400mm f2.8 VRII just might be faster in acquiring focus. Pretty sure the 1DMKIV is better at focus tracking though.
