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

The Tair-3S was one of the lens versions for the Photosniper set. The image shows two metal thumb wheels, the slimmer one as fastening screw to fix the lens on the sniper "gun" via its tripod thread. The thicker thumb wheel is attached to the lenses focusing ring and serves as second focusing handle. image by Ben Yurchenko (Image rights) |
