Pentax Super Takumar 55mm F1.8 M42 37101 Screw Mount Prime Lens -Clean-
This is a beautiful screw mount lens. It would be perfect for a classic M42 kit or adapter to mirrorless.
The glass is clean and scratch-free with no haze or fungus. There is a very light amount of dust between the elements that will not affect image quality.
The body shows light cosmetic wear and works perfectly. The focus has that wonderful Pentax smoothness. The aperture is dry and snappy.
This is a nice one.
