New In Pentax 50mm f2 SMC Pentax-M (7)

There’s moderate dust and coating damage inside that will slightly affect image quality. There’s also minor fungus. The fungus has been treated with UV light to neutralize it and prevent its spread. The focus is a bit dry/uneven, but works well enough. The aperture mechanism does not work properly, sometimes getting slightly stuck and not opening fully at wider apertures.
