Overview

The Macro-Takumar 50mm f/4 is a vintage M42 lens praised for excellent sharpness from f/5.6 to f/11, good contrast, and flare control. Weaknesses include corner softness at f/4, modest 1:2 magnification, and a slow f/4 aperture. Build is all-metal and solid, with smooth focus but a stiff aperture ring on some copies. It suits photographers seeking an affordable, characterful macro lens for adapted mirrorless or film, though infinity performance is acceptable.
