Must Have Pentax 50mm f2 SMC Pentax-M (7)

There’s moderate haze and scratching inside that will slightly affect use. There are also a few spots of fungus inside. The fungus has been treated with UV light to neutralize it and prevent its spread. The aperture mechanism is oily and slow, which will affect use. The rubber focusing grip is not attached properly and spins freely. It’s still usable, but annoying. Otherwise okay.
