There's visible noise already at ISO200, see http://tinyurl.com/33fh8t (frontside of speakers desk), but my impression is it's slightly better than the Ricoh GR-D. The fact it does not offer higher ISO than 800 looks like Sigma admits 1600 would be useless. The main advantage of the foveon sensor seems to be the better dynamic range. Btw this sensor has not DX format, but is smaller (1.7 crop factor not 1.5) Practical tests, handling and 1:1 comparisons with the GR-D II will tell us more. Meanwhile, I pack my R-D1 with a CV wide Didier >is the sigma DP-1 camera >http://www.dpreview.com/news/0801/08013108sigmadp1.asp >dx size cmos in a pocket camera!!
