Can you please tell me just how sharp indoor gym photos should be when shooting wide open at f/2.8? The margin of focusing error is huge because the dof is so small.

And how much noise is acceptable?

Should I bump up my iso in order to stop my lenses down?

I am using the 70-200 f/2.8 and the 24-70 f/2.8 on my canon 7D.

And how fast should I have the shutter speed set for practical purposes?

Just some practical tips would be appreciated.

can you use a flash? maybe try a fast prime?

It depends on just how fast a sport you are shooting. Indoor tennis or volleyball can be very fast at the moment of contact.
On my old 5D mkI which is pretty bad noise over 800 ISO, I have accepted the noise and shot at 1600 or 3200 ISO so I can try to keep my f stop slightly over 2.8 if possible.
Shutter of 1/125 can catch much, but faster is better.

If it is just too dark, I first give up ISO and bump that keeping my f-stop at 5.6 and shutter at 1/400 or faster
as it gets darker, I'll give up the f stop next since a shorter DOF is better than a blurry mess.
Finally as it becomes too dark for my old gear, I'm down to ISO 3200, f/2.8 and shutter 1/125 looking for emotions and reaction shots vs action.
Also the white balance can be way off under a gym's lights. I never use a flash during a game, the height of most hall's ceilings kills the flash's bounce also.
I shoot sports action on center AF point only and AI servo not on burst mode.

Most matches last for a long time, just try different camera setting and change them after 10 minutes. Try to find a few different places to shoot from during the game too.
If you have a hard time following the action looking through the lens, zoom out, then zoom in when you see something interesting develop. Have fun - Good Luck!!

you'll want to be at no less than 1/250 indoors, and that's pushing it. with your camera, though, you should be able to go up to iso3200 without a noise issue, and that should get you up to 1/500 or better, even in a cave. f/2.8 does have a short dof up close, but it's fine for action more than 30' away. if you can set up wireless strobes (with permission, of course), you can do lots of things; onboard flash are typically not allowed for indoor sports.

if you want some real specifics, you might pm MattO and/or look for some of his threads on sports shooting.

this gives me a good starting point... thank you.

i don't think i will be able to use any strobes but i will find out.
