Mir is a family of wide-angle photographic lenses developed and manufactured in the USSR. They are enlightened anastigmata containing from 5 to 9 lenses.
The majority of Mir lenses have a retrofocus design: their focal length is shorter than the rear segment, which makes it possible to use them as interchangeable for single-lens reflex cameras with a movable mirror.
- Mir-1V 2.8 / 37 (Vologda)
- Mir-1V 2.8 / 37 in an improved frame
The most famous and most popular of the lenses in the family. It was produced in various modifications for several decades and was in constant demand. The optical scheme was calculated in 1954 by the GOI team led by David Volosov on the basis of the Zeiss Flektogon 2.8 / 37 lens, developed in the GDR by Harry Zöllner. Due to successful design solutions, it was possible to reduce aberrations of higher orders, using cheaper grades of optical glass instead of the heavy crowns of the German prototype. The lens of the first editions of Mir-1 received the Grand Prix in 1958 at the World Exhibition in Brussels Expo-58.
The Mir-1 was the first Soviet retro-focus wide-angle lens, made on the principle of an “inverted telephoto lens” and suitable for use with single-lens reflex cameras. It was intended primarily as a replaceable lens for the latest Zenit cameras at that time and for several years remained the widest-angle lens for SLR cameras in the USSR. Variants for television cameras and other equipment were also produced. Major modifications:
- Mir-1 with M39 × 1 mount.
- Mir-1 Avtomat with bayonet mount for Kiev-10 and Kiev-15 SLR cameras.
- “Mir-1Ts” with a “C” mount for DSLR cameras of the “Zenit-4” family with a central lens shutter.
- Mir-1A – with replaceable adapter shank. After installing the appropriate adapter, it could be used on cameras with different mounts, including M42 × 1.
- Mir-1V (Vologda) is the most widespread lens from the entire Mir series, manufactured at VOMZ. In the 1990s, the frame was modernized, but the design and optical characteristics did not change. Fastening – thread M42 × 1.
- “Mir-1Sh” (“School”) – rejected by the quality control department of the “Mir-1V” party, intended for the centralized supply of school photo circles. Thread M42 × 1.
The Mir optical scheme was later used in a variety of lenses, which were united by the main feature: they were all wide-angle and were intended for single-lens reflex cameras. More than 20 lenses of the Mir family have been developed over several decades.
