Which would have a faster focus used on indoor/outdoor high school sports such as football (night time), basketball, baseball/softball?

Will be using flash, most likely a Sigma EF-500 Super, possibly a Sunpak 622 Super on the night time football if I can find a suitable module.

All will be shot handheld because I don't like the movement limitations imposed by a monopod. I have used the Sigma before on Nikon film cameras and really liked it.

Can't say which lens would have a faster focusing motor, but:

The Sigma @ F2.8 will inhale in twice as much light for the AutoFocusing sensor to work with than the Canon @ F4.
With this the 20D will be able to achieve focus easier, and it will successfully AF in lower light as well:!:

Also at F2.8 the 20D's high precision center focus point becomes active

I apologize for what is likely a very elementary nature of my questions.

But to give you a little background on my situation: I shoot sports for my local weekly newspaper and have been using an Olympus E-10 with pretty good results. Last week I shot with a borrowed 10D and 55-200mm Canon lens and was blown away. It rivaled the film cameras I had used a few years before.

Now I find that the 55-200mm lens is most likely crap and that the 20D is better for my pupose than the 10D.

I can't wait to begin shotting with my new combo. Sports photography will be fun again!

No problem, ask away it is the only way to learn:!:

Also yes, the 20D has a higher frame rate than the 10D, and better handeling of high ISO (up to ISO 3200 if you really want to push it.).
And with the digic-II processor in the 20D everything seems to be almost instant.
For a pro-sumer camera it's capabilities are most amazing.

Some late evening samples @ F2.8:
Both these images are at ISO 1600

Second image in this post is at ISO 3200

As for focus speed. The HSM speed is pretty much identical to the USM speed of Canon's. I have the 70-200 f/2.8 and the Canon 17-85 USM...no noticeable difference in focus speed...except the 2.8 lens is better at focusing in lower light...
