I'mdefinitelynot the person to give you an exclusive answer on this topic, but from reading other threads on this site I think you take some test shots with it. Like you'd set up an object at a fixed distance from your camera. Using a tripod and not changing any on-camera settings (such as sharpness), you would shoot with your new 70-200 and then shoot with an older lens at the same focal length. (Renting another 70-200 to test yours against would probably be the best way though).


Again, I'm not the authority, but it seems like renting a copy of the lens and shooting the same situation with same camera settings would show any defects in your lens.


Personal question: I'm planning on shooting soccer for my school this summer and a 70-200 f/2.8 non IS is on my wishlist. I've heard that the 70-200 is pretty useless w/o IS (200mm is too long w/o IS?). How do you like it? I suppose the usefulness of IS would depend on the situation, but how did it work for the lax game?
