Autofocus can benefit from f/2.8 lenses

This does not apply to canons' entry level DSLRS such as the rebel series right?

I would think that it does, because the XTi, XSi, and T1i use the AF system from the 20D and 30D. I do not think that it applies to the XS, XT, 10D, and earlier non-pro models, but I'm not sure. Daniel Browning would know. [:#] [H]
