Additional information:

The MC Zenitar 50 mm f/ 2 (Russian: "Зенитар") was designed in the 1990s to replace the outdated Gelios-44 lens. It has a multi-coating (MC). It was designed by Sergey Borisovich Byshkin, patent RU 2.290.675.

The construction and assembly technology have been considerably simplified, plastics and composite materials are in wide use. Nevertheless the lens renders the image of higher quality than that of the Gelios-44.

The MC Zenitar 50 mm f/ 2 came in two variants: with the M42 screw mount  (МС Zenitar 2/50) and the Pentax K-type bayonet mount  (МС Zenitar-К 2/50). The М2, К2  and М2s modifications were remarkable for further simplification and  cheapening of the construction.

Sharp in the center even wide open. Very nice bokeh effects. M42 version can be used on many different cameras with the proper adapter. Image quality far exceeds price, making it a great value. Color rendition and contrast are good. 


The biggest weakness is overall quality control on manufacturing. These lenses tend to vary from copy to copy on build quality. For example, my copy has aperture blades that are put together such that they form an oblong hexagon, rather than symmetric. This affects the shape of the bokeh artifacts. 


Overall, this is a remarkably nice lens for a small sum of money. Bang : Buck ratio is very favorable. I highly recommend picking one up. 

I use my copy primarly on a Canon 6D, but also a Canon t5i.  I have posted a longer review with additional photos here:
