I currently have the 70-200 f/4L (non IS), but I am considering replacing it by another lens with faster focusing speed. Does anyone have experience with both the 70-200 f/4L and the 200 f/2.8L II? How do their focusing speeds compare for moving objects? I'll be using it on a 5d mark ii. I'll be interested in a comparison (of the focusing speeds) with the 70-200 f/2.8L IS II as well. Let's assume that I'll be using the lenses at 200mm, if that is a factor in the comparison.
