here's a video with some initial impressions:
now, bear in mind I just wrapped up an EVIL review a few weeks ago. I had my EPM2, a borrowed X100, a borrowed NEX5r and a GX1. The oly won technically but I fell in love with the X100 because the X100s had been announced so I was ignoring it's AF issues. But now with the X100s the AF is NOT as good as the OMD which I'd hoped. It's much better but it still struggles in low light, especially in the <3' range. You do NOT need to mess with the macro setting for normal shooting anymore so that's great. But yeah, it's not oly fast AF wise and you will get red boxed from time to time. Is it much better? Yes. Is it as good as the 1 year old olympus OMD? Unfortunately no. But the IQ and everything else is pretty damned good so I think I'm still sticking with it.
