I am looking for some advice on taking pictures in gyms during volleyball & basketball games. I am using a Sony a330 lens right now, just got it earlier in the month. I had the opportunity to take some basketball pictures over the weekend. I used different settings each time to see what the results were, not really happy with any of them. My questions are: flash/no flash, auto, sports or P setting, change the ISO? Any advice at all will be very helpful.
