In that case, I'd say that 300mm will be too long for comfort - at a shooting distance of 75', 300mm on a crop body will frame 5.6' x 3.8'. That distance is longer than many of your shots will be, and still probably too tight for your subjects. I think you'll get a lot of use out of the 70-200mm f/2.8L IS II... Actually, you might find 200mm to be too long. At what's probably a reasonable shooting distance of 25', the 135mm f/2L will still frame a shot that's only about 5 basketballs wide (4' x 2.75').


You've mentioned the 85/1.8 and telephoto zooms and primes - you'll also want a wide lens for shots from under the hoop.
