MC 3M-5CA 500mm f/8
This lens was a so pleasant surprise, I am Hungarian I growed up under Russian pressure, so I didn’t have good opinion about any Russian products even Zenit camera etc. I had also bad imagine about mirror lens I love nice bokeh like East German lens has. I would make portraits from animals or just from their eyes, I couldn’t do that with my longest lens 300 mm Sigma. Long telephot lens prices are in the sky, I am amator photographer my budget is limited, so first of all i bought a Pentacon 500 mm f/5.6-22 MC lens, because price was reasonable and real glass lens. No succes with that see my review here. So after previous bad experience with “big gun”, I was shocked how sharp, how light weight this lens.It has nice massive all metal construction , but light weight like modern plastic ones. Highly recommended to everyone.

Rubinar and 3M-5CA produced today.
3M-5CA as MTO, but produced by another plant.
Rubinar sharper(He have other mirror design).
This lens benefits greatly by adding a lens hood, the f6.3 version, another lovely lens has it built in as do earlier versions of the lens, an absoloute delight to use might I add.
