with all that said, I really hope that Sigma eventually perfects the technology. I wonder, though, is that why should the primary colors in separate layers? why couldn\'t Sigma distribute the primary colors in all layers so Red channel would not have to suffer from too much noise?
The colors are detected based on photon diffusion depth, so you can\'t detect different colors at the same depth. Distributing the primary colors in the same depth means you need to put them next to each other, which gives you the same thing as an ordinary Bayer array sensor.
The concept behind the Foveon technology is to detect all 3 primaries at the same location, which gives better chroma resolution, but less accurate colors (and more noise overall).
