As depicted in the picture, you are considering the Pentax K mount, Albinar ADG MC brand (probably manufactured by Sigma) 135mm f/2.8 telephoto prime lens. It is in near mint condition with just a few signs of light, careful use Absolutely no dents, dings or significant scratches that I can see. Features of this lens include a fast maximum aperture of f/2.8 (for beautiful bokeh, the out of focus backgrounds in your portrait images), MC Multi-Coated glass for outstanding sharpness, contrast and color rendition, rock-solid construction not found in many lenses, the venerable Penta K-mount and more. The glass is clean and clear. The aperture blades are dry and snappy. The f/stop ring clicks positively and the focus action is silky-smooth. Very nice indeed. If you have been looking for a collection worthy Minolta MC mount lens, you should consider this item. Absolutely no disappointments! Asking $19.
