SMC Pentax 50mm f/1.2 - K Mount

SMC Pentax 50mm f/1.2 - Good Condition | Ultra-Fast Classic Standard Prime in Pentax K Mount

The SMC Pentax 50mm f/1.2 is one of the most extraordinary and sought-after standard primes ever produced — a flagship lens from Pentax's golden era that pushed the boundaries of optical engineering to deliver an exceptional f/1.2 maximum aperture with the legendary Super Multi Coating that Pentax is renowned for. The f/1.2 aperture places this lens in a rare and exclusive category — delivering extraordinary low-light performance, a beautifully shallow depth of field, and a three-dimensional rendering quality at wide apertures that few lenses of any era can match. The SMC (Super Multi Coating) ensures outstanding contrast, accurate colour rendition, and exceptional resistance to flare and ghosting across the entire aperture range. 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 1466609.
