>>3175324I actually own two Sigmas (a DP2 Merrill and an older model DP2–not the original, but I forget exactly which one).
The biggest dealbreaker is Sigma Photo Pro. The latest Foveon cameras are not supported by Adobe’s raw processors, and they’ve been unsupported for long enough that I’d wager they’re never gonna be. There’s a third-party command line until to convert to a DNG that anything can open, but the colors come out fucked in weird, un-unfuckable ways which pretty much kills the whole point of getting a Sigma. So you have to use Sigma Photo Pro, and it’s slow and ugly and awful and I hate it. Usually I just use it to output a tiff that Lightroom can eat, but it’s an annoying extra step for someone who has a Lightroom-based workflow.
At ISO 100 or 200, the pics are great. At 400, I wouldn’t kick ‘em out of bed. 800 and above, noise is bad. So bad that I usually just convert to black and white if I have one, and you’re back to “what’s the point?”
A lot of modern CMOS sensors nowadays are shipping without an antialias filter, which i think is actually a bigger contributor to foveon image quality than the foveon sensor. So I would say just get one of those instead.
