I'm puzzled. What sigma is doing with Foveon sensor refinement is rather exemplary. What is lacking (in my view) is mainly (lackluster) performance on processing and utility side, including SPP.

Granted, and we'd all like to see those areas improved. But even fixed they wouldn't solve the underlying limitations of the chip technology regarding poor low light/high iso performance, especially the purple/green blotches in the shadows. The only cure for that (if possible at all) is lots of R&D which none of us are sure Sigma actually has the resources for.

Are you sure the Foveon has to be a "low light//high iso performance" sensor? Can't it just be what it is? Or does it have be exactly the same as its Bayer competition?

The low ISOs I can live with, but not the purple/green blotches in the shadows. I shoot a lot of night shots and even at iso 50 on my SD15 the skies are horrible. If they were just noisy with a uniform color that would be fine and something that could be corrected using NR in PS. But no amount of noise reduction will eliminate purple/green blotches, it just smooths them over a bit but they're still very noticeable. IMHO this is the biggest problem the Foveon chip has.
