I think for the focusing speed, similar argument can be said about USM for Canon too. Beside the body, the lens play a big role too. :think:
Every system have it's Pros and Cons, that include Canon & Oly too. It's how one work around the limitations that matter the most.
yeah. pretty much depends on the lens and body combo. so the thing abt oly being faster is a moot point to me.
