This is the well-regarded Pentax screw mount 135mm portrait prime. It would be perfect for a classic m42 kit or adapted to mirrorless.
This lens is in excellent conditon with light cosmetic wear and works perfectly. There is a very slight amount of dust between the elements that will not affect image quality. The glass is clean and scratch-free and the mechanical action is very smooth.
It comes in the nice leather carrying case. This is a beautiful lens.
