Sigma

Sigma is known as a producer of SLR lenses. Its lenses are available for the different lens mount systems of several SLR camera makers.

Sigma was founded in 1961 by Michihiro Yamaki in Tokyo (Japan). Nowadays Sigma produces SLR camera models. The plant is 300 km north of Tokyo because it needs clean air and clean water for making optical precision products. It produces optical devices with glass free of arsenic and lead.

SLR cameras

Digital (SD series)

• SD-9 (3,4 MP, 2002)
• SD-10 (3,4 MP, 2004)
• SD-14 (14 MP, 2006)

The Sigma DSLR cameras are unique due to their Foveon sensor, instead of the common CCD or CMOS captors. Foveon sensor works much as film does in analogic cameras, having three coats which recognize each one of the primary colours. This produces a very intense chromatic impression on the photographies.

35mm film

• SA-5
• SA 7 QD (modern automatic SLR)
• SA 9 QD (modern automatic SLR, more features, exposure times down to 1/6000 sec)
