Pentax's dedicated macro lens from the Takumar era — the 50mm f/4 Super-Macro for extreme close-up work.
The Pentax Super-Macro-Takumar 50mm f/4 is a specialised macro lens from Pentax's M42-era Takumar lineup, designed for high-magnification close-up photography. The Super-Macro designation distinguishes it from the standard 50mm Macro-Takumar, indicating this version achieves higher magnification ratios. It was designed for scientific and technical close-up work.
Optical performance at macro distances is very good. The lens is optimised for close-up work rather than general photography. Sharpness at macro range is excellent with flat-field correction for reproducing flat documents and specimens. At infinity, performance may be less impressive as the optical design prioritises close-range performance. The f/4 aperture is typical for dedicated macros.
M42 screw mount. Filter thread is 49mm. Weight is approximately 230 grams — compact. Build quality is excellent with the precision metal construction typical of Super-Takumar lenses. The extended helicoid travel allows higher magnification ratios than standard lenses. Manual focus only with a smooth, precise helicoid essential for macro work.
Uncommon on the used market — specialised macro Takumars are less common than standard lenses. Check for smooth focus helicoid and clean optics. A specialised tool for macro photography. The M42 mount makes it adaptable to any mirrorless system for close-up work. Standard 50mm Takumars with extension tubes can achieve similar results.
