Contax 137 MA (1981–1984)
A 35mm film SLR from Yashica under the Contax brand, produced from 1981 to 1984 as an updated version of the 139 QM with added program mode.
Overview
The Contax 137 MA is a 35mm film single-lens reflex (SLR) camera. Yashica built it under the Contax brand from 1981 to 1984. It is an updated Contax 139 QM, and the main change is a fully automatic program exposure mode. Manual and aperture-priority modes are still there. A built-in motor drive handles automatic film advance and rewind.
Targeted at advanced amateur and semi-professional photographers, the 137 MA emphasizes reliable performance with minimal manual intervention, combining professional-grade build quality with emerging automation technologies of the early 1980s.
Design
The 137 MA has a fully automatic program exposure mode and keeps the manual and aperture-priority options, which made it one of the earliest professional-grade SLRs to offer all three. It has a built-in motor drive for automatic film handling. Contax designed it for technically demanding users.
Context
The 137 MA evolved from the Contax 139 QM and was introduced in 1981 for photographers who wanted a balance of automated convenience and manual control. Contax used it to modernize its SLR lineup with automatic exposure while keeping the precision expected from a professional camera system.
