Pentax Super-Takumar 135mm f3.5 m42 Screw Mount Lens
This is the well-regarded Pentax screw mount 135mm. There is a small spot on the front element with a slight wear in the coating, but it won't affect your image quality. Otherwise, the glass is clean and scratch-free and the mechanical action is very smooth. The body shows wear but this is just cosmetic. It comes with the shade in the original case.
