I'm sure all of us have thought the exact same and perhaps it's a stupid question on my part; I was wondering while reading this review: Sigma DP1 Merrill Review One should argue that Sigma could have a working :43: prototype in a matter of hours (and I'm sure they do). The FOVEON sensor is 20.7mm X 13.8mm. Well, the GH2 sensor is 19.3mmX13.4mm. I'm wondering how much work is involved in making a multi-aspect solution out of the FOVEON? For most aspect ratios, the drop in total Mp count would be insignificant (and that's not the point anyway). Sigma already has :43: mount lenses and could expand on them while taking advantage on existing lenses of course. A Sigma :43: camera could improve :43: position in the market. So what's the deal here? Sigma's sensor is not a silver bullet, nor it would challenge Sony sensors on all counts, but it would seriously take on much bigger sensors for a variety of needs, if implemented in our system. E.g. for a fashion shooter, FOVEON's resolution and lack of moire would be ideal, more so given that high ISO performance is not a pressing requirement.
