Additional information:


The Tair-11A 135 mm f/ 2.8 (Russian: "Таир") is    a fast telephoto lens.

Export model - Tair-11A.  It was produced at the KMZ, Krasnogorsk (the Krasnogorsk Mechanical Plant).

This is a fast coated lens. It is equipped with an iris preset aperture. The lens is equipped with a small built-in hood.

Its 20-blade aperture is nearly ideally round, which provides a beautiful out-of-focus blur when wide open. The lens is sharp and, at the same time, plastic.

As compared to 11 and 11-2 modifications, its resolution at the center and on the edges is much higher. Besides, the 11A modification features a more convenient (and more up-to-date) build. Its minimum focusing distance is 30 cm shorter and makes 1.2 m. It is shorter than his "relatives", but a bit heavier.

Modifications with the M42 screw mount are more common, though sometimes you can come across an M39 variant.

The A in the lens name means that the adapter can be attached to the lens - interchangeable KP-A/N mount (Rus. КП-А/Н), which makes it possible to use the Tair-11A on cameras with the N (Nikon F) bayonet mount, on Nikon cameras, and on the Zenit-11 camera.

Resolution according to the technical specifications (center/edge): 44/24 lpmm

Via adapters the 11A 135mm f/2.8 can be easily mounted on modern digital SLR cameras.

The model year of a Soviet lens can always be determined by the first two figures of its serial number.
