Vintage Lens (1987) "Mir-20 M" 3.5/20 mm, M42, very good condition.

From the first owner. "Mir-20 M" 3.5/20 - designed for SLR cameras with a frame size of 24x36 mm and a flange distance of 45.5 mm and has the ability to control the lens completely manually or with a jumping aperture (for Depth of Field Preview). "Mir-20M" 3.5/20 is equipped with a set of light filters. It has a first-generation anti-reflective coating. A large depth of field and a field of view angle of 96 degrees make it possible to emphasize various compositional details of the frame when shooting, to distinguish between the foreground, middle and background.
Feature - wide-angle (96 degrees), minimum focusing distance at aperture F3.5 - 18 cm, at F5.6 - from 18 cm to infinity, which can be very useful for street photography. Convenience - the small dimensions of the Mir-20M 3.5/20 lens and its weight create convenience for professional and amateur photography of architectural ensembles, interiors, and landscapes at close range. Mir-20 was created on the basis of the Flektogon 2.8/20 lens (Carl Zeiss Jena). The export version is a particularly careful assembly at the optical-mechanical plant in Krasnogorsk.
