Sears 28mm F2.8 with Pentax K Mount.  The lens is used and shows average wear for its age.  Focus and aperture function correctly.  The glass has some marks and dust associated with age, but appears to be clear of fungus, mold, and haze.   Includes one end cap and a filter.  It is completely manual – aperture and focus. It does have the “A” feature which allows for aperture adjustment from the camera body.  I mounted the lens on a digital SLR and took the photos of the flower in the listing.  The lens functions correctly. Shipment to the United States only. Delivery tracking provided.
