The Sirui 20mm T1.8 1.33x is an autofocus anamorphic cine lens for Sony E-mount, built for Super35 and near-full-frame sensors. Its STM motor adds fast, eye-tracking autofocus that most anamorphic lenses lack, and the 1.33x squeeze gives a 2.35:1 widescreen look in 16:9 without cropping. The wide 20mm view and 0.4m close focus make it useful for gimbal work, tight interiors and establishing shots. It is heavier and pricier than Sirui's manual anamorphics, and its 37mm image circle means full-frame bodies need cropping or a crop mode.

Owners and reviewers treat it as a practical autofocus anamorphic that makes the widescreen look easier to shoot solo. They praise the focus speed and the wide framing, and note the weight and the full-frame coverage limits.
The Sirui 20mm T1.8 1.33x anamorphic cine lens mounts on Sony E-mount cameras. It has a constant 1.33x squeeze factor, which gives a 2.35:1 widescreen aspect ratio in 16:9 mode without cropping. The 20mm focal length gives a horizontal field of view equivalent to a 22mm full-frame lens.
An STM stepping motor drives the autofocus, and the lens supports eye-tracking. You can switch between autofocus and manual focus. The T1.8 maximum aperture uses 11 aperture blades, and the minimum focus distance is 0.4m. Wide open, the bokeh is oval and lemon-shaped.
The image circle is 37mm. That suits S35 sensors and nearly covers full-frame cameras, though some vignetting occurs on full frame. Two flare characters are offered: a classic blue flare and a neutral flare. The lens is compact and lightweight enough for handheld, vehicle-mounted or gimbal-assisted shooting.
