Well, having handled one over the weekend I'm moderately impressed and slightly disappointed. Overall I think it's about the best of the compact system cameras around actually, it handles quite nicely. Big upsides are speed, AF and burst mode and seriously quick and very impressive. Big downside is manual control is as good as non existent it's so poor.
Image quality is good enough in my view, probably as good as the 4/3rds and to be honest if you care that much this isn't the market segment to be buying into.
It's too expensive, if it was £500 or so I'd buy one because, well because it's a nice toy, fits in my bag day to day and the idea of a f mount adaptor with a 2.7x crop is kinda funky.
