Does anyone use the 70-200mm VR for sports photography? I got one a couple of months ago to shoot basketball with a D1H. To my surprise I have fewer photos in focus than when I was using MF lenses. At first I thought it was my non-familiarity with all the various modes (normally I shoot continuous servo with only the center spot active), but after shooting about 10 games, I am convinced that there is something wrong with the lens. It is incredibly sharp and quick focusing if you are shooting a non-moving subject, but if you are trying to track a moving person, it fails dismally to lock focus on him/her. I even tried it in single-servo "focus priority" mode, and sometimes you can't tell from the photos what exactly it thought was in focus when it finally decided to let the shutter fire. So, anyone having success?
