Our take on the Sirui 20mm T1.8 1.33X S35 Anamorphic Lens

The Sirui 20mm T1.8 1.33x is a wide anamorphic lens for Sony E-mount cameras, built for Super35 sensors. It squeezes the image 1.33x, so footage shot in 16:9 opens up to a 2.4:1 widescreen frame with the oval bokeh and horizontal flares anamorphic shooters want. The fast T1.8 aperture keeps it usable in low light and gives shallow depth of field, while the wide 20mm view suits gimbal work, interiors and establishing shots. It is a manual-focus cine lens, so it competes with other budget anamorphics on character and build rather than autofocus or electronics.

What reviewers say

Owners of Sirui anamorphic lenses praise the anamorphic character, the fast aperture and the solid cine-style build for the money. Common complaints are softness wide open, especially at the edges, and the demands of manual focus on a wide lens.

What people mention
  • Anamorphic lookPraisedOwners like the oval bokeh and horizontal flares that give footage a filmic widescreen feel.
  • SharpnessMixedReviewers find it sharp stopped down but softer wide open, particularly toward the corners.
  • AperturePraisedThe T1.8 maximum aperture is valued for low-light shooting and shallow depth of field.
  • FocusCriticisedManual focus on a wide lens is described as demanding, and the autofocus claim does not match the lens.
  • BuildPraisedThe metal body and geared focus and aperture rings are seen as solid for cine rigs.
  • WeightCriticisedSome owners find it heavy for gimbal and handheld use compared with spherical primes.

Questions and answers

Does this lens autofocus?
No. It is a manual-focus cine lens with geared focus and aperture rings. You focus by hand or with a follow-focus unit.
Will it cover a full-frame sensor?
It is designed for Super35 sensors. On a full-frame body you will need to shoot in crop or Super35 mode to avoid heavy vignetting.
What aspect ratio does the 1.33x squeeze give?
Shot in 16:9 and desqueezed 1.33x, footage lands at roughly 2.4:1. That is the classic widescreen anamorphic frame.
Is the 20mm good for gimbal work?
Yes. The wide view is forgiving of small movements and suits establishing shots. Its weight means you should check your gimbal's payload.
Does it have electronic contacts?
No. There is no electronic communication with the camera, so aperture is set on the lens and EXIF data is not recorded.
What is in the box?
You get the lens with front and rear caps. A support foot or bracket varies by version, so check the specific listing.
