From the editor

The same lens was sold under the name Vivitar 28MM 1:2.8 AUTO VMC.

Under the name BAUER NEOVARON 1:2.8/28mm MULTICOATED, this lens was produced by Cosina in 1978 in a small number (maybe several hundred) of demo units for the Bauer RX1 35mm SLR camera (also made by Cosina), which was never put into mass production.

Under the name Miranda 28mm 1:2.8 MC, this lens was produced for the Miranda MS series 35mm SLR cameras with the Pentax K mount (also made by Cosina).

It is interesting that this lens was also produced under the name CARL ZEISS JENA F=28 mm 1:2.8 MC under licence from VEB CARL ZEISS JENA - not only for Pentax cameras, but also for other popular 35mm SLR cameras. In particular, we saw copies with Olympus OM and Praktica B mounts.
