smc Pentax-M 150mm f/3.5-32

The SMC Pentax-M 150 mm f/3.5 is a compact manual-focus telephoto prime introduced in 1977 and produced until 1986, designed for full-frame K-mount film cameras. It was part of the second-generation “M” series lenses, offering a slightly faster aperture and more compact build than its K-series predecessor, while maintaining Pentax’s hallmark of optical clarity and mechanical precision.  Optically, it features a 5-element - 5-group design with Super Multi-Coating (SMC) and a 6-blade automatic diaphragm. The lens stops down to f/32, focuses as close as 1.8 meters, and delivers a 0.1× magnification ratio. It uses a 49 mm filter thread, weighs just 290 g, and measures 63 × 75 mm. It includes a built-in sliding hood, a manual aperture ring (no “A” setting), and was typically sold with a dedicated hard case. There’s no internal focusing or weather sealing, but the lens is fully compatible with all Pentax K-mount bodies, including digital cameras with manual exposure support.  Absolutely no marks, scratches, dents, dings, worn finish, grime or extreme use. The glass is clear with no haze, mold, fungus, scratches, cleaning marks, or noticeable dust.  The built in lens hood slides in and out easily.  The aperture ring clicks nicely and the focus ring operates smoothly.  The blades are clean and free of any oil or debris.
