Our take on the Sirui 20mm T1.8 1.33x Anamorphic Cine Lens

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.

What reviewers say

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.

What people mention
  • AutofocusPraisedOwners say the STM motor focuses fast and tracks eyes reliably for video.
  • WeightCriticisedReviewers call it heavy and front-loaded, which strains gimbals and long handheld takes.
  • CoverageMixedThe 37mm image circle covers Super35 well but vignettes or crops on full-frame bodies.
  • SqueezePraisedThe 1.33x factor gives a 2.35:1 frame in 16:9 without cropping.
  • FlareMixedThe anamorphic flare and oval bokeh are loved by some and seen as too strong by others.

About the Sirui 20mm T1.8 1.33x Anamorphic Cine Lens

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.

Questions and answers

Does it autofocus on Sony bodies?
Yes. The STM motor supports autofocus and eye tracking on Sony E-mount cameras, and you can switch to manual focus.
Will it cover a full-frame sensor?
Only partly. The 37mm image circle suits Super35; on full frame you will see vignetting or need a crop mode.
What aspect ratio does it give?
With the 1.33x squeeze in 16:9 mode you get about 2.35:1 without cropping the frame.
How close can it focus?
The minimum focus distance is 0.4m, close for an anamorphic lens and useful for tight shots.
What filter size does it take?
It accepts 77mm filters, so standard cine and ND filters fit.
Is it good for gimbal work?
The autofocus and wide view help, but the lens is heavy, so check your gimbal's payload.
