Description: Buy with Confidence Buy with Confidence From a highly rated seller with 20+ years of presence on eBay *** Just Serviced *** SMC Pentax 28mm f/3.5 Prime Lens, Manual Focus Lens works 100%, excellent glass, mechanics Mint, like new appearance The lens is from the first generation of K mount lenses when Pentax switched from M42 to K mount, known as SMC-K lenses. Built very sturdy to last, with heft of metal and glass. Focus helicoid is made of brass - never seen on later generations. Many fans of Pentax manual focus lenses prefer this first generation K lenses. This SMC-K 28mm/3.5, while we hesitate to call it rare, is seen much less often than other Pentax lenses, especially in the US market. It has got excellent reviews for its sharpness and colors. With its solid metal build it is also a joy to use. Note this lens is totally different from the compact SMC-M 28mm/3.5. Those SMC-K lenses are dated back to 1970's and are about 50 years old. They generally need service to restore its 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 for sale here has just been completely 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. Focus helicoids have be rebuilt with new modern helicoid grease applied. The lens will serve you many more years without you worrying about those issues mentioned above. The lens glass is clear and bright. Glass has no scratch, fungus or haze. If you shine strong light through the lens, as usual you may see a couple of tiny dusts - this is normal and has no effects on lens performance. Aperture blades has no oil and are snappy. Aperture ring clicks to every stop positively. With the helicoids completely rebuilt, the focus action is smooth with proper resistance and consistent across the range, with the feel of a new lens - that's how brass helicoids perform after rebulid. Filter threads are good - filter screws on/off w/o effort. Lens barrel is mint and looks super clean, nice and presentable. We don't find noticeable wear marks like bright spots or scuffs on the barrel. All lettering is crisp and bright. No ding, dent or crack. See photos for cosmetics Includes a pair of generic caps and a TIffen USA UV filter as shown. The filter glass is in excellent condition.
