Our take on the SIRUI 20mm T1.8 1.33X S35 Frame Autofocus Anamorphic Lens

The Sirui 20mm T1.8 is a wide-angle anamorphic lens with autofocus, built for Super 35 sensors. It squeezes a 1.33x anamorphic image onto the frame, giving 2.4:1 widescreen after desqueeze, oval bokeh and horizontal flares. The fast T1.8 aperture and autofocus make it far easier to use than manual-focus anamorphics, which is why owners rate it highly. It suits filmmakers who want the anamorphic look on gimbal or handheld work without a focus puller.

Questions and answers

Does it work on full-frame cameras?
No. It is designed for Super 35 sensors. On a full-frame body you would need to shoot in a crop mode.
What aspect ratio does the 1.33x squeeze give?
On a 16:9 sensor it desqueezes to roughly 2.4:1, the standard widescreen anamorphic ratio.
Does autofocus work with my camera?
Autofocus depends on the camera body and mount adapter. Check that your body supports AF with this lens mount before buying.
Is it good for handheld and gimbal work?
Yes. The wide 20mm view and light weight suit gimbal and handheld shooting, and autofocus helps when you are moving.
What is in the box?
The lens comes with front and rear caps. Check the listing for any case or support accessories included.
How does it compare with the 40mm version?
The 20mm is wider for establishing shots and tight spaces. The 40mm gives a tighter, more portrait-like anamorphic look.
Where is the SIRUI 20mm T1.8 1.33X S35 Frame Autofocus Anamorphic Lens cheapest?
