SMC Pentax 50mm f/2

SMC Pentax 50mm f/2 - Good Condition | Classic Standard Prime in Pentax K Mount

The SMC Pentax 50mm f/2 is a beautifully crafted standard prime from Asahi Optical Co.'s respected SMC Pentax lens lineup — the predecessor to the celebrated M-series and a lens that established the optical and coating standards that made Pentax glass so highly regarded worldwide. The SMC (Super Multi Coating) designation reflects Pentax's advanced multi-layer coating technology — delivering outstanding contrast, accurate colour rendition, and exceptional resistance to flare and ghosting. Slightly larger and more substantial in build than its M-series successor, it has a tactile and reassuring quality that many photographers prefer. In Pentax K mount, it pairs naturally with the full range of Pentax K mount film and digital bodies and adapts effortlessly to modern mirrorless systems. Serial number SR 1466609.
