The Asahi Pentax Super-Takumar 50mm f/1.4 is a fast standard prime lens in the M42 screw mount, produced for Pentax Spotmatic-era 35mm SLRs. Designed as a general-purpose normal lens, it pairs a bright f/1.4 maximum aperture with the well-regarded Takumar optical pedigree of the late 1960s and early 1970s.

At UK auction in recent years, hammer prices for the Super-Takumar 50mm f/1.4 have been modest, with a recorded 2024 saleroom result of £60 — a wholesale level achieved before buyer's and seller's commission. With only one verified sale in the dataset, the lens is worth roughly that figure today for a clean user-grade copy, and it typically sells for a similar price in the auction market, though pristine examples and the early radioactive thoriated-glass version (sometimes nicknamed the "Atomic Takumar") can command a premium when condition and provenance are documented.
