Pentax-M SMC 28mm f2.8 K Mount Wide Angle Prime Lens -Very Clean-
It is amazing how big modern lenses have gotten (and how consumers have tolerated this). A lovely gem like this 28mm really puts it in perspective. It is a tiny lens with great specs and 49mm filter threading.
This lens is in excellent condition with moderate cosmetic wear. The glass is clean and scratch free and the aperture is dry and snappy. The mechanical action is smooth. Caps are included.
