 Like the previous models, it uses a Foveon X3 direct image sensor, this time with an improved pixel count of 2652 × 1768 × 3 photo-elements (4.7 million locations, 14.1 million total photo-elements).Since there are three layers of sensor elements for each pixel location, one each for red, green, and blue, Sigma and Foveon count 14 megapixels, counting all individual single-color sensor elements.Similarly, companies selling Bayer sensor cameras also count single-color sensor elements as pixels, as does Fujifilm with its Super CCD cameras, in which both large and small photo-sensors under the same color filter and microlens are counted as pixels.
