A sharp prime lens from Pentax SMC-A line, their last generation of manual focus lenses. Its "A" setting makes using it with modern digital SLRs a lot easier.

These old manual focus lenses (nearly 40 years old) generally require service to restore their performance. The main culprit is the grease in the lens. After decades of use (or disuse) it usually has separated and the lighter oil part has evaporated and condensed onto the internal glass surfaces to form a film of numerous tiny oil droplets (oil haze) - very detrimental to image quality as it softens the image quite a lot. The oil haze is much worse than a little swirls of cleaning mark on the coating or a few sporadic dust particles inside the lens.

Some of the lenses, if they have experienced hot/cold conditions for example in a storage unit, the lighter oil may have got onto the blades to cause a sluggish or completely stuck aperture. Even if not yet on blades, often the oil has crept close to the aperture cartridge and not before long it will get onto the blades. The grease on the focus helicoids may have deteriorated (separated, lighter oil is gone, heavier part has gummed up) to cause a stiff focus ring or very loose focus action with some play. If the lens has been on beach or in dusty environment, the focus action may be gritty.

The lens here has just been serviced. We cleaned it inside out. Internal glass surfaces have been cleaned and oil in vicinity of the aperture cartridge as well as gummed up grease at various places has been cleaned off. Helicoids have been rebuilt with modern grease applied. The lens will serve you many more years without you worrying about those issues mentioned above.

The lens has clear and bright glass. No scratch, fungus or haze. If you shine strong light through the lens you may find a few tiny dusts. This is normal and has no effects on lens performance. Aperture blades has no oil and are snappy. The focus ring is smooth, consistent and with proper resistance.  Filter threads are good - filters screw on/off without effort. Lens is working 100% including the "A" function - tested on camera.

Cosmetically it is excellent condition, with just a few very minor signs of scuffs on the barrel. The lens looks quite clean with all lettering crisp and bright. No dent or crack. Please see photos for cosmetic conditions.

Includes a pair of generic caps as shown.
