The Tair-3 300mm 1:4.5 is a fast and heavy metal telephoto lens for SLRs with M42 lens screw-mount. 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 optimzed 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.
