Sigma SA mount - LightPoint

Sigma introduced the SA mount in 1992, as evolution of the old (1976) M42 and newer (1983) Pentax K mount. It has been used by full frame and APS size sensor cameras/lenses.

In 2018 Sigma announced that it discontinues development of SA-mount camera focusing instead on the Leica L mount through the L-alliance with Panasonic and Leica, while SA-mount lenses should be still produced.
