PL mount. This lens is the PL-mount version.

The Anamorphic Look. The Orion Anamorphic lenses provide a clean, oval shaped bokeh you might expect out of more expensive anamorphics. The Orions produce a unique but well-controlled anamorphic lens flare. If you want dat J.J. Abrams look tho, this lens will give it to you. Shining a light toward the lens in the frame will produce a wonderful blue-hued flare that goes almost edge to edge depending on light strength.

Standardized Features. All the Orion Anamorphic lenses have the same front lens diameters, focus, and iris ring positions. This allows for super-fast lens changes just by swinging your matte box and dropping your follow focus without moving their positions. Markings in feet appear on both sides making it easy for ACs and focus-pullers to do their jobs. The entire Orion series boasts the same industry-prevalent 0.8 pitch gears and 114mm front diameters.

Compatibility. A 31mm image circle means the Orions can cover 4:3 ANA 23.76 × 17.89mm in Arri Alexa-land. Over on the RED side, this lens can cover Helium 8K 6:5 ANA, Gemini 5K 6:5 ANA, and Monstro 7K+ 6:5 ANA.
