The Sigma SD10 is a digital single-lens reflex camera (DSLR) manufactured by the Sigma Corporation of Japan. It was announced on October 27, 2003, and is an evolution of the previous SD9 model, addressing many of the shortcomings of that camera. The Sigma SD10 is unique amongst DSLRs in that it uses a full-colour Foveon sensor (Instead of one with a Colour Filter Array) and that it only produces raw format images that require post-processing on a computer.
