I never had been in a volleyball game, but I'm sure that you can freeze a fast moving car at 1/500 and at 1/250 you can deal with jumping guitar players. Maybe you should try to shot at a lower speed.

Image quality, as ever, it's a matter of how large do you print your pictures. The 135 f/2 it's more than enough for a double page in a well printed magazine.
