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.
