※Note: The mount is a highly versatile M42 screw mount. (K mount was selected for convenience as there was no suitable option in the size selection.) [Product Name] Asahi Pentax Super-Takumar 55mm f1.8 (Early Model) Serial Number: 1538392 [Product Features] This is the "early model" of the Super-Takumar, renowned as the definitive old lens. Unlike the later model (Atom lens), it has a rare optical design that does not suffer from the "yellowing" characteristic of radioactive lenses. It is ideal for those who want to achieve both clear color reproduction and the beautiful rainbow flare unique to Takumar lenses. [Maintenance Performed] The lens has been disassembled and cleaned internally for this listing. There is no mold or cloudiness, and the view remains remarkably clear for its age. [Condition] • Optics: No yellowing, mold, or cloudiness that would affect image quality. In excellent condition. • Exterior: Minor scuffs due to age, but no major dents or scratches. This unit has been well-cared for. • Operation: The focus ring (helicoid) is smooth, and the aperture blades operate crisply. • Bonus: The attached lens filter is included as is. [Accessories] • Lens body • Lens filter (attached) • Front cap • Rear cap [Important Notes] This is a manual focus old lens. While the unit is in very good condition overall, please understand that it is a product from several decades ago before purchasing.
