At f/2.8, the 70-200/2.8II is at least as sharp as the 70-200/4 at f/4, if not sharper. If sharpness + speed is your goal, the 70-200/2.8II is the answer. The only downside is that it is bigger and twice as heavy as the f/4.

There is an "emperor's new clothes" situation in this thread regarding the fundamental "sharpness" question.

Basically, comparing these lenses on the basis of sharpness is irrelevant in the real world. Both are excellent lenses in terms of image sharpness - basically having the best performance available in lenses such as these. While a technician may be able to scope out some small but measurable differences between them on the test bench, these amount to essentially nothing at all in the photographs you'll produce.

Asking about the effect on the sharpness of your photographs from choosing the f/2.8 or the f/4 IS 70-200mm lenses is sort of like asking about the effect on value of choosing between four quarters and a dollar bill.

The important decision points are entirely about things other than sharpness in this case.
