The Sigma dp series is equipped with Foveon, the only sensor in the world that can take in all optical information as it is with a film-like layer structure. The overwhelmingly rich color gradation, generated by the vertical color separation system sensor, has the same power of expression as the texture seen by the eyes, making it possible to reproduce colors without discontinuity even in monotone black-and-white gradation. The dp Quattro series was born from an uncompromising review of all the components, radicalizing our direction towards "cameras for creation", the philosophy of Sigma, and specializing in essential performance to bring professional artistic expression closer.
