Pentax Super-Macro-Takumar 50mm f/4 - M42 Mount

The Super-Macro-Takumar 50mm f/4 is a dedicated macro lens for the M42 screw mount system. It is designed for high-magnification photography, offering excellent sharpness and a flat field of focus. The lens features a deeply recessed front element, which often eliminates the need for a lens hood, and a long focus throw for precise manual adjustments at close distances. On the used market, ensure the exceptionally long helicoid moves smoothly across its entire range without binding. The M42 thread should be clean and free from cross-threading damage. SDS checks for oil on the aperture blades, which can be an issue in older macro lenses, and verifies that the optical coatings are intact.
