Just wondering which will be better at focusing (speed and accuracy) for a 20D. I know the F4L is highly rated in that regard, but doesn't the 20D allow for somesort of "super focus" mode when coupled w/ a 2.8 lens and the center focus point? Thanks!

Yes it does.

Your choice is speed (Sigma f2.8) v Weight (Canon F4)

Decide which is most important and choose accordingly. There's tons of info on here :)
