==== Summary ====
The SMC Pentax-A 50mm f/1.2 is a legendary ultra-fast standard prime lens for Pentax K-mount 35mm and full-frame digital SLRs, produced from 1984 to 2004. It features a 7-element/6-group optical design, a 9-blade automatic diaphragm, and Pentax’s Super Multi-Coating (SMC) for enhanced contrast, color fidelity, and flare resistance. With a blazing f/1.2 maximum aperture, it delivers exceptional low-light performance and dreamy, shallow depth-of-field—making it a favorite for portraiture and artistic photography. The lens focuses down to 0.45m, offers a 0.15× magnification, and uses a 52mm filter thread. It weighs 345g, measures 65 × 49mm, and includes an “A” setting on the aperture ring, enabling full Program, Shutter-priority, and Aperture-priority modes on compatible Pentax bodies. While it lacks autofocus, internal focusing, and weather sealing, it’s built solidly with a metal barrel and smooth manual focus throw—ideal for precise control.
