I was thinking of the canon EF 135mm f/2L USM

Does anyone have any experience with the combination taking indoor sports pictures? Or any other lens suggestions?

-F2 is great. 135 might be a bit long on a digital body indoors. Twist on a zoomie and verify what you can use from a focal length standpoint.

Remember that white balance or RAW is your friend.

Learn to anticipate and pre-aim.

Thinkahead about what moves/plays in your sport make a good shot.

Get where you can get faces.

Fill the card... take lots of shots. Then keep everything organized and ranked on your hard drives.

- #1 rule of serious digicam photography! Take far more photos than you hope to use - then get home and sort through them for the "keepers." Since each additional photo costs about zero - and one reusable card takes the equivalent of several rolls of 35mm film - this is essential. No processing costs but your time for the bulk of photos you'll not use, either.
