Hi. I've currently got an AF-S 80-200 2.8D. I'm going to at some point upgrade this to the VR and if I can do it soon for a good price I'll do it. But I'm wondering on the logical next step on the tele range. I shoot at school some, and starting next year I think I'll be shooting a lot of sports. We have numerous good athletic programs, and I'll do a lot of shooting on the field and some in the gym. For the gym my 2.8 lens will probably suffice, but outdoors there's a lot of field and the potential for some great action shots. I've been thinking about the 300 f/4, probably AF-S budget permitting (otherwise i'd have to get the older AF version used), and I wanted to hear some comments, especially from any sports shooters out there. Interested in how it does as far as sharpness, focus speed, and general results. Thanks in advance for your advice.
