Pentax Super-Takumar 50mm f/1.4 Ver 1

(INSERT SINGLE HERO IMAGE HERE - other images below in media section)

Summary

The Super-Takumar 50mm f/1.4 (8-element variant) is a legendary M42 screw-mount prime lens produced by Asahi Optical Co. from 1964 to 1966. Designed as a “Planar killer,” it features a rare 8-element/6-group optical formula with a cemented triplet at the rear—expensive to manufacture and discontinued after just two years. This early version delivers exceptional sharpness, rich contrast, and smooth bokeh, especially from f/2.8 onward, with a fast f/1.4 aperture ideal for low-light and portrait work. It has a 6-blade diaphragm, 49mm filter thread, and minimum focus distance of 0.45m. Weighing 245g and measuring 61.5 × 43mm, it’s built in a solid all-metal body with engraved “Super-Takumar 1:1.4/50” markings. nique identifiers include a slightly protruding rear element, an infrared focus mark to the right of the “4” on the depth-of-field scale, and an “A M” switch (not “Auto/Man”). Unlike later 7-element versions, this model does not contain thorium glass and is non-radioactive. Its distinctive rendering and rarity have made it a cult favorite among collectors, portrait photographers, and vintage lens enthusiasts. Like all M42 Takumar lenses, it can be adapted to all Pentax DSLRs and modern mirrorless cameras.
