Series of lenses “Zenitar”

Zenitar is the name of the lenses intended for Zenit small format cameras and manufactured by the Krasnogorsk Mechanical Plant. By this brand are also long-focus lenses Telezenitar and zoom lenses Variozenitar . The name “Zenitar” and its derivatives do not describe any specific optical device, and was assigned to lenses of various types intended for the “Zenith” equipment. The brand appeared in the late 1970s after the decision to unify the names of the KMZ model range named after I. Zvereva as the most memorable in the international market.

Standard lens of the camera “Zenit-19” – “Zenitar-M” 1,7 / 50

Well known and widely used wide-angle Zenitar-M 16mm

Types of lenses

The most famous normal “Zenitars” 1.7 / 50 and 1.4 / 50 with a high aperture are a complicated type of “double Gauss” and are similar to the Volna lenses developed at GOI. The basis for these developments was the Ultron lens, created by the German optician Albrecht  Wilhelm Tronnier for Schneider Kreuznach in 1937.

In addition to high-aperture normal lenses, which were produced as standard lenses for Zenith reflexes, under the Zenitar brand, retrofocus wide-angle and distortion optics with optical schemes developed at GOI under the names Mir and Zodiac were produced. Later, Telezenitar long-focus lenses appeared, developed by KMZ independently. After the restructuring under this brand, the development of the latest optics began, including those designed to work with foreign photographic equipment. Lenses “MC Zenitar-M2s” 2/50, “MC Zenitar-M” 2.8 / 16 and their modifications with bayonet mount are still produced.

All lenses in the Zenitar series are equipped with a jumping aperture mechanism. Almost all, except for the earliest models, such as “Zenitar-M” 1.7 / 50, and some “Telezenitar”, have multi-layer optical coating (the “MS” index before the name). Zenitar lenses, depending on the modification, have a threaded М42 × 1 or bayonet mounts. To designate the type of mount, one more letter is added to the lens name: C – Canon EF, H – Nikon F, K – Pentax K, E – Sony E.
