Do Sigma lenses on a Canon system focus as fast and as accurately as Canon lenses?

thanks, Mike

I guess that depends on the type of motor the lens uses... i have a Sigma 28-105 which focuses right away, a little noisy but good fast af.

My Sigma 100-300 EX HSM is as fast as anything else I've tried. I played with a Canon 70-200 2.8 (Non IS) and I couldn't tell a difference on my XT.

My 135-400 DG is as fast as my two non-USM Canon lenses. It's loud (just like the Canons), but it's fast enough for me.

My Sigma 30/1.4 focuses faster than my 50/1.4, but a tiny bit slower than my 85/1.8 (which is VERY fast).
