Asahi Pentax Super Takumar 105mm f/2.8 M42 MF Lens [Exc+5] from Japan #697*
I cleaned the lens by the disinfectant. The aperture blades on this lens work fine. The diaphragm blades of this lens are beautiful and do not have oil. No noticeable scratches on the lens. No fungus or haze inside the lens.
