This is an Auto Ultranar MC 1:2.8 135mm f/2.8 Lens for Asahi Pentax K (KR) Mount Cameras No. 810030

The glass is clean; no fungus, haze, or scratches, just some minor dust that will not affect the picture quality.

The housing shows only SLIGHT signs of wear. The focus is smooth, but I can't get the aperture to function, so please bid accordingly. 

The pictures are of the actual item up for bid. Please contact seller with any questions.
