Sigma SD1
The Sigma SD1 is a digital SLR camera produced by the Sigma Corporation of Japan. The camera uses a Foveon X3 sensor, which comprises 3 layers of 4800 x 3200 pixels (46 megapixels), giving much higher chromatic resolution than the equivalent Bayer array. It uses a Milbeaut image processor. The Foveon sensor does not use an aliasing filter, thus further improving the resolution.
