Pentax Asahi SMC-M 50mm f/2 Standard Prime Lens – Pentax K Mount, Manual Focus, 7 Blades, Coated Optics (Renewed)

The Pentax Asahi SMC-M 50mm f/2 is a compact, fast standard prime from Pentax’s legendary M-series lens lineup. Introduced in the late 1970s, it pairs the acclaimed Super Multi-Coating (SMC) optical formula with a lightweight aluminum barrel — a combination that made it one of the most popular lenses of its era and continues to make it sought after today. With a bright f/2 maximum aperture, this 50mm delivers versatile performance for street photography, portraiture, and everyday film shooting. The smooth manual focus ring and 7-blade aperture produce reliably pleasing out-of-focus rendering. It mounts natively on all Pentax K-mount bodies and adapts easily to mirrorless systems, making it an excellent choice for photographers bridging film and digital workflows.
