The high ISO pictures, like this one http://tinyurl.com/yspg6v (pink surface left of "Circus", dark grey surface below), do not look significantly better than from smaller-sized sensors. It really seems that Sigma could not take the full advantage of it's bigger sensor, though the noise is slightly lower in average as with the GR-D at ISO800. I am also somehow disappointed by the lens. If they make a fixed lens only in f4.0 instead of f2.5 or f2.8, one may expect the heck of a razor sharp thing, with even reproduction from center to corner. But Phil Askeys DP1 hands-on preview snapshots http://tinyurl.com/3baups show a rather average optical performance, clearly below the Ricoh lens. The corners are rather soft, see this one http://tinyurl.com/yvw8le (top right). The Auto-White balance seems not very spot on (first inside picture/Sigma booth); but that's a problem of many digital cameras and can be resolved by editing the RAW file. All in all, I do not have the feeling that Sigma has produced a milestone with that camera, but tries to catch up others, breathlessly and with some delay. It's a pity. I would have expected a bit more and I guess I'll pass on this one. Didier At 16:10 02.02.2008, mehrdad wrote: >http://dc.watch.impress.co.jp/cda/review/2008/02/02/7893.html
