The production of the Tair series started in the mid 50s of the last century and ended in 2005.
Lens for SLR cameras with M42 screw connection. This lens is installed on modern SLR and mirrorless cameras through the appropriate adapter. Read the article about adapters.
In 1958, the Tair-3FS lens (Photosniper-3 kit) won the Grand Prix in Brussels, and a year later was awarded the II degree Diploma of the All-Union Exhibition of Economic Achievements of the USSR. The Tair-12C lens used in the PhotoSniper-3 kit has satisfactory optical qualities (see the TX table at the end of the article), but at the same time has a lot of weight (about one and a half kilograms).

Tair-3FS lens layout
The calculation of the optical scheme was carried out David Samuilovich Volosov (later, author of the book "Photographic Optics" (1971, p. 339).
Types of lenses Tair
Tair-3S 300mm can be found with both simple and multi-coating (MC). Early copies (Tair-3FS) were produced in a white case. Tair-3S has constructively different brothers Tair-11A, 33, 38C, 56, forming a whole series that has been produced for almost 60 years. Tair 3A - one might say, the twin brother of Tair-3C (differences in housings and diaphragm setting mechanisms).
An experimental model of the Tair-3T (television) lens is known, which could be used with high-resolution photographic materials (up to 130 lines / mm versus 68 for serial models). At different times, the lenses were produced by the Kazan Optical and Mechanical Plant (KOMZ), Krasnogorsk plant named after S.A. Zverev and Zagorsk Optical and Mechanical Plant, Sergiev Posad.
Physical data of Tair-3FS
The diameter of the thread for the Tair-3C 300mm filters is 72 mm, the lens is really huge. The length is about 30 centimeters, the weight is one and a half kilograms.
The frame of the Tair-3C lens is made of aluminum. The main weight is the front adhesive lenses. The lens requires a tripod, since in low light even at f / 4.5 we will get guaranteed image blur if we don't find a stop. In sunny weather, the lens works wonders. The use of Tair-3 lenses was recommended if it was necessary to obtain good image quality.
Despite the apparent solidity of the construction, the lens is quite delicate and requires careful attitude to itself. The slightest distortion of the lenses (even by 0,03mm) can damage the picture. In particular, anterior gluing produces noticeable aberrations when the geometry is violated.
