This is a little disappointing about the autofocus if it is the same with the final model. Contrast based autofocus in DSLR's besides the Panasonic G1 is horrible. (2-3 seconds to focus)
For the G1 and GH1 Panasonic developed an incredibly fast new imager AF system and has been praised for getting contrast detect AF speeds up to near those offered by entry-level phase detect focus systems (as used on all SLRs). Unfortunately Panasonic didn't share that technology with Olympus, and the E-P1 uses essentially the same focus system as cameras such as the E-620, meaning that it feels sluggish even compared to most compacts (that said, we're playing with a very early IP (initial production) unit here - without the final firmware - so will reserve judgment until we've got the finished product).
