Overview

The Super-Takumar 150mm f/4 is a compact manual-focus telephoto lens with a 5-element design (Pentax Forum). Optically, it is sharper wide open at f/4 than several 135mm lenses stopped down (diediemustdive), but it flares easily, so a hood is recommended (diediemustdive). Build quality is typical Takumar, though the sample reviewed had fungus issues. It suits photographers who value sharpness and character over flare resistance, and who are willing to use a hood.
