can read abt the SD10 here.

the foevon sensor, according to overseas reviews, does produce stunning
RAW ONLY images, which must be processed using the supplied software. its a 3.4 MP (effective) cam but with 3 photo detectors for each pixel location (fuzzy maths.. but dats how sigma comes up with 10.6 million sensor photo detectors) - 1 detector per color (RGB). i've yet to see any local photogs i know who used this. btw, the last set dat was sold here in Buy/Sell was sold by nikonsiao, on behalf of his fren.
there's only 1 little problem with using the SD10 - u have to use sigma SA-mount lenses. ie u have very limited selection (if any) lenses available locally.
