===== Pentax SMC 50mm f/1.2 ===== {{ :lens:pentax_smc_50mm_f1.2.png?250|}} ==== 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. ==== Tech Specs ==== | Manufacturer |Pentax| | Series |K Series Prime| | Model |SMC| | Focal Length |50mm| | Max Aperture |f/1.2| | Min Aperture |f/22| | Format |Full-Frame| | Image Circle |-| | Minimum Focus |45cm| | Focus Rotation |°| | Iris Blades |8| | Optical Design |7/6| | Squeeze |none| | Front Diameter |65mm| | Filter Thread |52mm| | Focus/Zoom Rod |none| | Native Mount |Pentax K| | Data Protocol |none| | Length |48.5mm| | Weight |385g| | Body Telescope |-| | Body Material |-| | Focus Drive |-| | Iris Drive |-| | Zoom Drive |-| ==== History ==== Country of Origin: \\ Release Date: 1975 \\ Launch Price: \\ Design Revisions: \\ ==== Service ==== Service Manual: (Insert link to manual here) \\ \\ Full CLA: **TBD hrs.**\\ \\ ==== Cine-Mod ==== Focus Ring O.D.: -\\ Zoom Ring O.D.: -\\ Iris Ring O.D.: -\\ De-click Y/N: -\\ Additional Notes: \\ ==== Notes ==== ==== Media ====
