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 lenses and other accessories that are compatible with the cameras produced by other companies.[1]

The company was founded in 1961 by Michihiro Yamaki, who was Sigma's CEO until his death at age 78 in 2012.[2]

Sigma produces products to work with cameras from Canon, Nikon, Pentax, Sony, Olympus and Panasonic, as well as for their own cameras.

Sigma also makes lenses under the Quantaray name, which are 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 DP1 and DP2, high-end compact P&S cameras, also use the Foveon X3 image sensor, which gives them a much larger sensor than other cameras of this type.

Sigma is the world's largest independent lens manufacturer and is a family-owned business.[3]

Cameras[edit]

Sigma has made a number of film SLR cameras, including the SA-300, SA-5, SA-7 and SA-9. Their latest consumer digital SLR is the SD15. During Photokina 2010, Sigma announced their new flagship DSLR camera, the SD1. SD1 features a new 46MP Foveon X3 sensor with 1.5x crop, as opposed to the 1.7x crop of previous models.[4]

All Sigma SLR and DSLR cameras use the Sigma SA mount, which is mechanically similar to the Pentax K mount and electrically an adaptation of the Canon EF lens mount lens control system.

Sigma also produces high-end compact digital cameras, the Sigma DP1 and Sigma DP2, using similar 14 MP Foveon X3 image sensors to that in the Sigma SD14 DSLR and launched in 2012 the Sigma SD1 Merrill, Sigma DP2 Merrill and Sigma DP1 Merrill using a 23.5 x 15.7 mm sensor. In February 2013, Sigma released the DP3 Merrill, with a 50mm F/2.8 lens (equivalent to 75mm on a 35mm SLR camera).

Lenses[edit]

Sigma makes autofocus lenses for the Sigma SA, Canon EF, Nikon F, Minolta/Sony α, Pentax K and Four Thirds lens mounts. Each lens may not be available in all mounts, and may lack certain features (such as HSM) on certain mounts. There have been some complaints of quality control and assurance issues of lens manufacturing.[5][6]

In August 2013, Sigma announced that starting the following month, it would offer a mount conversion service for its newest "Global Vision" lenses—those with either an "A" (Art), "C" (Contemporary), or "S" (Sport) as part of their model name. For a cost that varies with lens and market—from $80 to $250 in the U.S., not including shipping costs—owners can send their lenses to their local Sigma company, which in turn sends them to Japan for mount replacement, including calibration and optimization for the new camera system. Lenses designed for DSLRs can be converted to Canon EF, Nikon F, Pentax K, Sigma SA, or Sony A mounts; those designed for MILCs can be converted to Micro Four Thirds or Sony E-mount.[7]

Designations[edit]

Sigma 200–500mm F2.8 EX DG displayed at the 2008 photokina

  • HSM — "Hyper-Sonic Motor", either in-lens ultrasonic motor or micro-motor, analogous to Nikon SWM (AF-S) (ultra-sonic or micro-motor), Canon USM (ultrasonic or micro-motor), Minolta/Konica Minolta/Sony SSM (ultrasonic motor) or Sony SAM (micro-motor), etc.
  • A — "Art Series", large aperture prime and zoom lenses, high optical performance. USB dock compatible. Part of 2013 lens lineup restructuring.
  • C — "Contemporary Series", combining optical performance with compactness. USB dock compatible. Part of 2013 lens lineup restructuring.
