Mir 1B 37mm f/2.8
M42
Overview
The Mir 1B 37mm f/2.8 is a Soviet wide-angle that punches above its weight. Based on Zeiss designs but evolved into something distinctly Soviet, it offers genuine quality at budget prices. The 37mm focal length — slightly wider than 35mm — gives a unique perspective that many photographers prefer.
Verdict: The budget wide-angle champion. If you need a wide lens and can't justify expensive glass, the Mir 1B delivers.

Bokeh
The 10-blade aperture provides a pleasing, rounded bokeh, which becomes more pronounced when the lens is stopped down.

Flare resistance
