===== Pentax-M SMC 85mm f/2 ===== {{ :lens:pentax-m_smc_85mm_f2.png?300|}} ==== Summary ==== The SMC Pentax-M 85mm f/2 is a compact manual-focus short telephoto prime introduced in 1977 and produced until 1984, designed for full-frame K-mount film cameras. It was part of the M-series, known for its smaller size and lighter weight compared to the earlier K-series lenses, and was positioned as a portrait-friendly alternative to the larger and faster 85mm f/1.8 and f/1.4 options. It features a 5-element - 4-group optical design, Super Multi-Coating (SMC), and a 6-blade automatic diaphragm. The lens stops down to f/22, focuses as close as 85cm, and delivers 0.13× magnification. It uses a 49mm filter thread, weighs 251g, and measures 63 × 46mm. It includes a clip-on PH-R49 hood, a plastic front cap, and was often sold with a dedicated hard case. There’s no “A” setting on the aperture ring, so it’s best used in manual or aperture-priority modes. ==== Tech Specs ==== | Manufacturer |Pentax| | Series |M Series Prime| | Model |SMC| | Focal Length |85mm| | Max Aperture |f/2| | Min Aperture |f/22| | Format |Full-Frame| | Image Circle |-| | Minimum Focus |85cm| | Focus Rotation |°| | Iris Blades |6| | Optical Design |5/4| | Squeeze |none| | Front Diameter |63mm| | Filter Thread |49mm| | Focus/Zoom Rod |none| | Native Mount |Pentax K| | Data Protocol |none| | Length |46mm| | Weight |251g| | Body Telescope |-| | Body Material |-| | Focus Drive |-| | Iris Drive |-| | Zoom Drive |-| ==== History ==== Country of Origin: \\ Release Date: 1977 \\ 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 ====
