I don't know if I have the job yet, but I'm looking for some info./pointers on shooting a swim team outdoors. I will have the 17-55 2.8 IS on the 40D and know I'll need to keep the aperture no wider than, say, 5.6? I obviously don't want some people to be out of focus! What about the reflection of the water? Does that tend to pose a problem? Any input would be greatly appreciated. Like I said, I'm not 100% sure if I'd be doing this yet, just curious. Thanks.
Ah, forgot to add, these will be team photos - not 'action' shots.
