Let me introduce you to an excellent vintage lens, production of the USSR.
 
Industar-69 28mm F/2.8 USSR Wide Angle Pancake Lens for Chaika M39.

The lens has been serviced, cleaned and lubricated. Ready to use.

The Industar-69 28 mm f/ 2.8 is a fast, wide-angle prime lens for the Chaika half-frame camera.

May be of interest to owners of compact mirrorless cameras with interchangeable lenses. It can be used on Zorki / Leica, but taking into account the fact that the distance scale on the lens will need to be marked differently.

It should be borne in mind that the working lengths of the systems do not match (27.5 mm for Chaika, versus 28.8 mm for Leica). When attaching the lens directly to rangefinders (LSM systems) or using the L39-adapter (your mirrorless system), infinity focusing will not be possible. A simple modification of the lens or adapter used will be required. It should also be borne in mind that this lens is not full-frame, i.e. On full-frame cameras, strong vignetting will be observed.

The photo is of the actual item for sale!

Through appropriate adapter this lens can be installed on any modern mirrorless cameras, such as Sony NEX, Samsung NX, Olympus micro 4/3 and more. (Adapter not included).

I have for sale the same lenses already converted to infinity, complete with an adapter for different systems. See my products.

See the photos, made by me the same lens on a Sony NEX camera, APS-C!
