Sigma Corporation (株式会社シグマ Kabushiki-gaisha Shiguma?) is a Japanese company, manufacturing cameras, lenses, flashes and other photographic accessories. All Sigma products are produced in the company's own Aizu factory in Bandai, Fukushima, Japan. Although Sigma produces several camera models, the company is best known for producing high quality lenses and other accessories that are compatible with the cameras produced by other companies.
The company was founded in 1961 by Michihiro Yamaki, who was Sigma's CEO until his death at age 78 in 2012.
Sigma products work with cameras from Canon, Nikon, Pentax, Sony, Olympus and Panasonic, as well as their own cameras.
Sigma has also made lenses under the Quantaray name, which have been sold exclusively by Ritz Camera. Similarly, Sigma lenses were sold exclusively by the former Wolf Camera, but following the merger of Wolf and Ritz, both brands can be purchased.
Sigma's digital SLRs, the SD9, SD10, SD14 and SD15 and the latest SD1 are unusual in their use of the Foveon X3 image sensor. All use the SA lens mount. The Sigma DP series of high-end compact P&S cameras also use the Foveon X3 sensor, which gives them a much larger sensor than other cameras of this type.
