The Sirui 40mm T1.8 1.33X S35 is an autofocus anamorphic lens that compresses the field of view to capture more information along the horizontal axis and create a cinematic widescreen frame. It produces horizontal lens flares and oval bokeh.
Its optical design includes ED elements and aspherical glass to reduce chromatic aberrations and deliver edge-to-edge sharpness.
