Shooting some hockey tomorrow, using 70-200 IS 2.8 (MK1) on a 5D. Plan to shoot at iso 1600 and using center point focus, probably AI Servo focus mode. Should I even bother leaving IS on when I'm shooting or don't bother? Will it slow the focus down at all? They are 6 years old and under so the hockey won't be that fast so hopefully I can get some sharp shots with 1/500 sec.
