The '''Tair-3 300mm 1:4.5''' is a fast and heavy metal [[telephoto]] lens made by [[KMZ]] for [[SLR]]s with [[M42]] lens screw-mount (and also  made with a 39mm mount for earlier Zenit cameras). Its version ''Tair-3A'' has a design as common heavy M42 system lens with own tripod thread, delivered in a set with yellow and orange filter, hood, and quiver. Quite round iris diaphragm and well arranged lens elements make it a decent tele shooter, even with aperture wide open. Minimum focusing distance is 2.2 metres.

Other versions of the Tair-3 were optimized for use in the [[Zenit Photosniper]] set, for example the ''Tair-3AS''. Sniper versions usually had a better lens coating as advantage, but minimum focusing distance 3.3 metres as disadvantage.

There are two thumb wheels between the ''sniper gun'' and the lens´s sniper version's lens barrel, the gun's narrow one to fix the lens via its tripod thread, and the lens's thick one with distance scale which is its special focusing device instead of a common focusing ring.
