Pentax Takumar macro in M42 mount, quality close-range optics with flat-field correction at rock-bottom pricing.
The Pentax Takumar 50mm f/4 Macro is a true macro lens in M42 screw mount, designed for close-up photography with optimised close-range optical correction. The Takumar macro lenses share the same attention to optical quality as the standard Takumar primes, with additional flat-field correction for sharp reproduction of flat subjects.
The 50mm focal length provides a standard perspective for macro work, and the lens achieves 1:2 magnification without accessories, reaching 1:1 with the optional extension tube. The f/4 maximum aperture keeps the lens compact while providing adequate depth of field at macro distances where DOF is naturally very shallow.
Build quality is excellent Pentax standard with an all-metal barrel, extended focusing helicoid for close-range travel, and the precise mechanical feel characteristic of Takumar lenses. The M42 mount provides universal adaptability to modern mirrorless cameras for digital macro work.
The Takumar 50mm f/4 Macro is a superb value on the used market for macro photography, offering Takumar optical quality optimised for close-range work at minimal cost. The M42 mount makes it usable on virtually any camera, and the manual focus experience is actually advantageous for precise macro focusing.
