But the camera retained its promise nonetheless. Using a multi-layered Foveon X3 image chip, the SD14 promised superb color capture by allocating a separate analog chip to each of the 3 primary colors, allowing 3 color properties per each pixel of the image instead of the normal 1. While Sigma had debuted the chip in the past, their last camera was released back in 2004. And things have changed a bit since then.
