The Mir series of lenses is a family of wide-angle photographic lenses designed and produced in the USSR. They are enlightened anastigmata containing from 5 to 9 lenses.
Most Mir lenses have a retrofocus design: their focal length less than the rear section, which allows them to be used as interchangeable for single-lens reflex cameras with a movable mirror.
World 1
Mir-1 was the first Soviet retrofocus wide-angle, made on the principle of "inverted telephoto" 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 in the USSR the widest-angle lens for SLR cameras. 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) - the most common lens from the entire Mir series, produced at VOMZ. In the 1990s frame modernized, but the device and optical characteristics have not changed. 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.
