I'll be honest with you if you use live view in 60D, auto focus speed is a disaster. Takes few second to focus an object. Not sure why but if you don't use the live view. it works fine.
I really hate the auto focus in 60 D with live view mode.
If you can tolerate the extra noise, using "quick mode" focusing in live view is faster. Amazing, but it is much quicker for the camera to lower the miror, autofocus using the focus sensors, and raise the mirror back up, versus trying to autofocus using the main sensor. (It's almost funny to watch it focus in live mode. Mine seems to make large steps first, then tick-tick-tick small steps trying to focus, then back to large steps, repeat, etc.)
