History

Sensors, mounts and lenses
Foveon and Bayer. Most digital cameras use a Bayer sensor: a mosaic of red, green and blue filters, with one color per pixel and the missing colors calculated. A Foveon sensor records all three colors at each pixel in three stacked layers. The SD Quattro (2016) used a newer generation of this sensor, called Foveon Quattro. Sigma’s current cameras use conventional Bayer sensors.
L mount. Sigma’s current cameras and many of its lenses.
Lenses for other mounts. Sigma lenses are made for Sony E, Fujifilm X, Canon RF, Nikon Z and other mounts. Lenses marked DG DN are designed for full-frame mirrorless cameras.
