MIR-1B 37mm F2.8

The design of this lens was based on Carl Zeiss Jena Flektogon 35 mm f / 2.8 of metal construction. Although it was first produced by KMZ, the lens itself has had many different manufacturers with varying degrees of quality. The sharpness of the image is of good quality and with good color reproduction. The chromatic aberrations are well controlled although the reflections are quite difficult to contain without the use of a parasol.
