Manual and Autofocus Anamorphic Prime
Capture cinematic widescreen footage with the aid of an autofocus option using the Sirui 20mm T1.8 1.33x S35 AF Anamorphic Lens. This innovative prime lens uses an STM motor for fast, accurate autofocus while offering manual focus for more complicated shots handled by a camera assistant/focus puller. It has a fast T1.8 maximum aperture lens that is ideal for low-light capture and for creating distinctive bokeh effects.
The lens is offered in two options : NEUTRAL flares (the flares remain the colour of the light source) or BLUE flares that are a classic feature of the anamorphic format.
