I'm thinking of buying one of the sigma cameras, as I like the concept of the foveon sensor, and having read Mike's article re image quality comparison with the 5d http://ddisoftware.com/tech/articles/may-2007-sigma-sd14-14mp-4-6mp/
, and also many other reviews, I think the dp1 or dp2 would match nicely wrt image quality to my current Canon cameras, but in format easier to fit in a pocket. Having just looked at a list of supported cameras on one of the dcraw pages http://www.cybercom.net/~dcoffin/dcraw/
, dcraw appears to support the Sigma SD14, and I am wondering if it now supports the dp1/2, or if by simply changing the file extension, or other minor details, if Qimage could in fact could then read in the dp1/2 raw files as SD14's. I do not know when the list of dcraw supported cameras was last updated.
It appears that Sigma are updating the peripherals/speed of operation, on a regular basis (a third version of the dp1, and a second version of the dp2 recently released), but afaik they are keeping the same sensor for all the foveon based cameras they make, so I have the feeling that the technology may be around for a while.
