The Sirui 50mm f/1.8 Anamorphic 1.33x Lens, with an MFT mount, is designed for APS-C cameras and increases the horizontal FOV by 33% in comparison with traditional 50mm APS-C lenses. The result is equivalent to a wider, 37.5mm APS-C lens. After a de-squeeze, the captured image is displayed in an anamorphic 2.4:1 format in a 16:9 setting. This fast f/1.8 lens is designed with an aluminum housing and features optics with multilayer Nano coatings. It has renowned Schott optical glass lens elements and delivers rectangular aspect ratios, long horizontal lens flares, and oval bokeh.
