I wanted to get an idea of the focus speed of the X-E1. (And I am not sure if this has already been answered somewhere.) I realize that this is really lens-specific, but was thinking of the general feel. Is it similar to the X10 speed? An E-PL2 and a Panasonic 20mm? FYI - I've only experienced E-PL1, E-PL2, E-PL3, G3, X10. FWIW, I didn't find any one of them particularly frustrating (even the E-PL1). Slow, but not terribly frustrating.
