Asahi Pentax 50mm f/1.4

{"overview":"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. 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.","buying_guide":"Inspect the front and rear elements carefully for fungus, haze and coating scratches, as Takumars of this era often show internal haze that softens contrast. Check the aperture blades for oil and confirm they snap cleanly, rotate the focus ring to feel for stiffness or dried grease, and look for any signs of element separation around the cemented groups.
