Vologda 37mm f2.8 MIR-1B for M42

Description

The Vologda 37mm f2.8 MIR-1B lens is a classic Soviet-made wide angle lens. Of course, it’s a bit weird: the preset diaphragm system appears to work in the opposite direction of the markings, and it focuses past infinity. Why? I do not know. Takes a perfectly decent picture, though. Includes original bubble case and instructions (in Russian, naturally)
