Re: POLL - Sigma and Foveon
Agreed, though in reality most are not. AFAIK, only Canon, Sony, Panasonic, possibly Samsung, and now Sigma amongst major players produce their sensors in-house.
Sigma's main problem in the SLR field has perhaps always been that those who buy into it are limiting themselves to marque lenses only (that's not to say that the company doesn't make some very fine lenses), and so far some of the more esoteric objectives available from, especially, Canon & Nikon aren't there.
Back in the days when I had an SA-5, the camera was generally pretty good (build quality was a touch on the plasticky side, but that's not unique) apart from the AF, which was always somewhat hesitant. From what I know, Sigma haven't really caught up yet on that front.
