The Mir-26 45 mm f/ 3.5(Russian: "Мир") is a wide-angle lens with an instant-return aperture and a single-layer coating for medium format cameras with the B and the Pentacon 6 bayonet mounts (the Mir-26B 3.5/45 variant) and the V bayonet mount for the Salyut and the Kiev-88 (Mir-26V 3.5/45).

This is a good lens according its mechanical and optical quality. The optical scheme was based on the Carl Zeiss Jena Flektogon 50 mm f/ 4, but it was redesigned. In particular, lens speed was increased.
The image generated by the Mir-26 45 mm f/ 3.5 is characterized by good sharpness, high contrast, and insignificant aberration.
Back light is not handled well.
Via adapters it can be used on modern SRL and mirrorless cameras.
It is possible to mount the lens on the shift lens adapter for the Canon EOS (see Picture 4) and other modern digital cameras, thus turning it into a shift-lens.
The Mir-26 45 mm f/ 3.5 is rather frequent and inexpensive in the secondary market. The preference should be given either to the exported lenses (the name is written with Latin characters: Mir-26) or to the lenses with the quality mark.
