3M-5A-MC 500mm f/8 is mirror-meniscus lens with multilayer-coated achromatic. Option "CA" characterized by reduced size and weight. The ZM-5A is a classic sample of Soviet-era engineering and workmanship. It is a 500 mm telephoto mirror lens based on the design of a known Soviet engineer Maksutov.
We have built a lens hood, which hides the focus ring.
As you can see has 4 holes for the tripod, arranged in pairs of different diameters under 90 degrees.
Important note: because the lens has a huge overrun at infinity, it can be put on any sort of camera.
The letter "A" in the title means a removable liner. That is, removing a shank, you can put on the other. For example, the Nikon. The letters "ZM" decrypted "zerkal'nyi (Mirror) meniscus."
The main feature of the mirror-meniscus lens is that they give so-called "annular" bokeh, ie circle of confusion in the area will be a circle with a hole in the center.
