Manufacturer description #1

The high-quality "Таир-11А" lens is intended for use on "Зенит" type SLR cameras for outdoor shooting of distant objects, but can also be used for other types of photography, especially for portraits. It has an aperture presetting device. It is used with the latest domestic and foreign cameras with М42х1 thread and a working distance of 45.5 mm. The lens has a removable adapter ring for using lenses on cameras with М39х1 thread.

Light transmission: no less than 0,80. Resolving power, lines/mm (no less than): in the center of the field: 44; at the edges of the field: 24.

Manufacturer description #2

The photographic lens "Таир-11А" is interchangeable for cameras of the "Зенит" type (with a curtain shutter), designed for shooting of distant objects, but can also be used for other types of photography, especially for shooting portraits.

The lens is available in two versions:

with the usual achromatic coating - "Таир-11А";

with multi-layer achromatic coating (МС) - "МС Таир-11А".

With the use of multi-layer achromatic coating, a significant increase in the light transmission and almost complete elimination of harmful scattered light is achieved, which makes it possible to photograph even when there are bright light sources (sun, lamp, etc.) in the field of view.

Light transmission, no less than: 0.80 (Таир-11А); 0.91 (МС Таир-11А).

Manufacturer description #3

The photographic lens "Таир-11А" is a four-element anastigmat with coated optical surfaces, designed for "Зенит" type SLR cameras with a frame format of 24X36 mm.

The long focal length, large aperture and high resolving power allow the lens to be used for shooting distant objects, animals and birds, group scenes, architectural details, sports moments, as well as for portrait work, especially in low light.

The lens barrel is equipped with a retractable sun hood.

When using the lens on cameras with other working distances, interchangeable adapter rings are used.

From the editor

The lens was produced by the Krasnogorsk Mechanical Plant (USSR).

The manufacturer description mentiones the multi-coated version of the lens, but it was never put into production.

One of the instructions gives slightly different weight and dimensions: 600g, max. dia. 70mm x length of 110mm.

Notes

• The lens has an interchangeable mount that is mechanically identical to the T2 interchangeable mount. In the USSR, the following interchangeable mount adapters were produced: "КП-А/42" (T2 - M42x1/45.5), "КП-А/39" (T2 - M39x1/45.2), "КП-А/К" (T2 - Pentax K), "КП-А/Н" (T2 - Nikon F). "КП" is an abbreviation for "Кольцо переходное", which means "Adapter ring".
