The only other limitation is that I don't have a fast zoom lens. I am shooting exclusively with a Canon 50mm f/1.8. I really like this lens but shooting anything further out on the court is next to impossible. I do get some shots in focus out on the court, there are just not enough of them.

One of the biggest lessons I have learned to get great individual shots is taking advantage of pre-game warmups. The teams tend to do repetitive drills in warmups and it allows me to stay pointing in a single spot or zone and take shots of each player in succession. The two shots above are two of my best that I have gotten and they were both in the same pre-game. There are at least another half dozen from this pre-game that turned out very well.

One of the other lessons that I learned is to get underneath the basket. Most of the action takes place there and most of that action is physical. This causes a lot of great faces and reactions as you can see in the two pictures above. This goes double for high school girls basketball. Girls, without trying to insult them, don't play as fast and jump as high as the boys so they are closer together and more contact tends to happen.
When I get under the basket, I try to get as low to the ground as I can. This creates a more dramatic angle and I've found it helps to get a piggy-back from the lights in the ceiling.
