The SIRUI anamorphic lens produces an image circle large enough to cover APS-C sensors. Since the field of view is anamorphic, it is wider than any conventional 24mm lens. It increases the field of view by up to 33%. With a sensor setting of 16:9, the resulting image has an aspect ratio of 2.4:1 widescreen.

This SIRUI lens has the typical characteristics of a true anamorphic cinema lens, such as backlight effects and lens effects (flares) and oval bokeh.

The lens is equipped with a manual focus.
