Production sample photos now posted at DP Review. Perhaps nothing spectacular, but three encouraging observations nevertheless:
* The lens is very sharp, even wide open.
* Reds, in these photos at least, don't look odd (only the photographer knows for sure).
* ISO 800 performance doesn't stink.
To sum up: compared to the DP1 you get an extra stop with the lens plus a higher usable ISO range--perhaps meaning two-stops of enhanced low-light performance. For those wanting a "normal" focal length, this lens does the trick. Best US price seems to be $650. Those teetering on the precipice may want to await Oly's µ4/3 June rollout, but Foveon fans can jump now.
