Overview

The Tair-3S 300mm f/4.5 is a heavy (1550g), all-metal vintage lens with a unique rotary focus dial that aids stability but makes focusing difficult for moving subjects. Optically, it delivers a distinctive retro look with low contrast and smooth bokeh from 16 aperture blades, but sharpness and chromatic aberration improve significantly when stopped down to f/5.6 or f/8. It suits users seeking a characterful, budget telephoto for static subjects on a tripod, but not for critical sharpness wide open.
