SMC Pentax-A 135mm F/2.8 Manual Focus Prime Lens

Excellent Glass and Mechanics, Excellent Appearance, Lens works 100%

A great fast standard lens from the SMC-A series. Just completely serviced.

These SMC-A's are the last manual focus Pentax lenses with the "A" setting. It is a lot easier to use those SMC-A lenses on modern DSLRs, for which Pentax decided to remove the mechanical aperture coupler.

When buying those nearly 40 years old lenses keep in mind that they generally need 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 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. New helicoid 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 it you may see a couple of tiny dusts - this is normal and has no effects on lens performance.

Mechanically excellent. Aperture blades has no oil. Snappy. The focus ring is smooth with proper resistance. The aperture ring clicks to stops and "A" setting locks/unlocks as it should. Filter threads are good - filter screws on/off without effort. The built-in sliding shade slides smoothly and stay where you let go.

Lens is working 100% including the "A" function - tested on camera.

Cosmetically the lens barrel is in EX+ to Mint- condition. The minus is for few small scuffs on the finish, and a slight hint of bright spots on the sharp edges of the knurled aperture ring on the underside of the lens. The lens overall is clean, nice and presentable, with all lettering crisp and bright. No dent or crack. Please see photos for cosmetic conditions.

Includes a pair of caps as shown.

This lens is for 35mm Pentax cameras - previous buyer returned because it does not fit her 645 (medium format)
