The result is equivalent to a wider 26.3mm APS-C lens. After de-squeezing, 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. Made with renowned Schott optical glass lens elements, it produces rectangular aspect ratios, long horizontal lens flares, and oval bokeh. 2.8' minimum focusing distance.The lens is equipped with a manual focus. 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 produces a shallow depth of field and oval bokeh with its 10 aperture blades. While the lens has a robust housing, it's also designed to be lightweight for use with your compact MFT/APS-C camera.
