135mm f/3.5 prime lens, SMC PENTAX-M. - Brand: SMC PENTAX-M - Focal Length: 135mm - Maximum Aperture: f/3.5 - Country of Manufacture: Japan - Lens Type: Prime I have roughly checked the operation. There are scratches on the edge of the hood. There are also wiping scratches on the rear element of the lens. There appear to be no dust, mold, or significant scratches or peeling of the coating that would affect the image quality. This is a practical item. Thank you for looking.
