From the editor

A version of the Auto Cosinon 50/1.9 without the manual aperture mode.

The specifications are identical to the Auto Cosinon 50/1.8 and were taken from the instruction manual for the Cosina 1000S 35mm SLR camera and the instruction manual (November 1975) for the Vivitar 400/SL 35mm SLR camera (a rebranded Cosina 4000S).

The same lens was sold under the name Vivitar 50MM 1:1.9 AUTO.
