I'll be interested in hearing more about this. When Olympus gets it right, they get it very right. When wrong ... well, you know. The hands-on experience sounds problematic. And there's a sample gallery.
Off the top, the 20.4MP is a little low for my needs. I often crop severely after shoots - many times I have a limited envelope of subject and location availability, and must frame for safety, not for creativity [no do-overs]. Thank goodness I can fall back on 25+ years of Photoshop experience. More MP buys me that grace.
