Sirui 50mm F/1.8 Anamorphic Overview

The Sirui 50mm f/1.8 Anamorphic 1.33x Lens, with an X-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.

One of the features of this lens is that it produces horizontal blue streaks with less stray light, which Sirui calls sci-fi horizontal flares. A key aspect of anamorphic lenses is highlighted oval bokeh, and this lens achieves a shallow depth of field and oval bokeh with its 10 aperture blades. While the lens has a robust housing, its also designed to be lightweight for use with your compact APS-C camera.
