    Overview

    The МС Яшма-4 300 mm f/2.8 is a Soviet-era manual focus telephoto lens known for its fast aperture and solid build. Optically, it delivers good sharpness in the center but suffers from softness and chromatic aberration at the edges, especially wide open. The lens is heavy and built like a tank, with smooth focusing but a stiff aperture ring. It suits photographers who value speed and character over modern edge-to-edge sharpness, and who are comfortable with manual operation.
