The Tair-56 150 mm f/ 2.8  is a fast telephoto prime for 35 mm SLR cameras with the M42 screw mount. This is a coated 4-element anastigmat.

There was also a modification (Tair-56A) with an interchangeable mount. The lens with the analogous optical scheme designed for 35 mm motion picture cameras came under the name of OKS1-150-1 (Rus. ОКС1-150-1). The Tair-56 150 mm f/ 2.8 lens came in small lots and is very rare at present.
