Mir 1 USSR LENS wide angle 37 mm f2.8 for SLR M42 Canon Nikon Zenit
Mir -1 - interchangeable wide-angle fast lens. Equipped with an iris diaphragm with a pre-installation device
The optical design was designed by D. S. Volosov in 1954 for glass formulations available in the USSR based on the Carl Zeiss Jena Flektogon 35mmf/2.8 lens, produced after World War II by the Carl Zeiss plant in Jena. Has a diverging meniscus as the first lens, which significantly reduces vignetting when shooting at an open aperture
Recommended for all types of filming. It was noted that it is especially valuable when shooting, requiring special sharpness of all image details.
The lens really produces a fairly sharp image. At the same time, the “volume” of the image is well preserved.
