This is an interesting review. I like his posted samples much more than many critics who rushed their reviews without really taking many solid photos yet.
He has a followup about doing a professional shoot with the E-M5, nicely illustrated like his review. He even mentions in passing that the E-M5 beats his D700 for IQ at low ISO?!
On the downside he did experience a number of camera lockups. Hope they can fix that bug soon...
