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 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’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 DP1 and DP2, 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. International Buyers – Please Note.
