Mr T, IMO you have it; 70-200 2.8. You may, rarely, find it a bit too tight, but on the whole for a basketball game....its the do all lens.


I've photographed various sports in decently lighted gyms w/a 40D, 17-85 IS 4/5.6. Granted, I had to bump the ISO to 1600 for some shots and they weren't Sports Illustrated caliber, but still very good under the circumstances.


The 2.8 will make all the difference in the world w/a 7D...lower ISO and better noise control....with great versatility.


I'm doing some college hockey games in the next few weeks and I will be shooting w/a 70-200 IS 2.8....whether it will be rented or purchased depends upon how much damage I do buying gifts for Christmas. LOL


Regards


Bill
