==== Summary ====
The SMC Pentax 50mm f/1.2 is a legendary ultra-fast manual-focus prime lens for Pentax K-mount 35mm and full-frame digital SLRs, produced from 1975 to 1984. With a bright f/1.2 maximum aperture, it excels in low-light conditions and delivers razor-thin depth-of-field for dreamy, cinematic bokeh. Its 7-element/6-group optical design, 8-blade automatic diaphragm, and Super Multi-Coating (SMC) ensure excellent contrast, color fidelity, and flare resistance—even wide open. The lens focuses down to 0.45m, uses a 52mm filter thread, and weighs a hefty 385g in a robust 65 × 48.5mm all-metal barrel. It features a long, smooth focus throw ideal for precise manual focusing, especially in portraiture and creative photography. Engraved markings vary slightly between early (SMC PENTAX 1:1.2/50) and later (smc PENTAX 1:1.2 50mm) versions. Though challenging to master wide open, it rewards patient shooters with stunning rendering and remains one of the fastest and most iconic Pentax K-mount lenses ever made.
