Nice 40mm f/2.8 SMC Pentax-M "pancake" lens


This lens is in very good optical and cosmetic condition. The glass and coating are excellent. Viewed with an LED flashlight there is no fungus, mold, or fog. There is a small amount of internal dust and debris. There is no oil on the iris blades, which snap down properly. The Pentax case is not the original type, but the lens fits into it snugly. The listing includes a generic front cap and the correct Asahi back cap.


This lens was donated to be sold to support the Argus Museum. It is not part of the Argus Museum collection.
