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

The Sirui 20mm T1.8 is a wide-angle anamorphic lens for mirrorless cameras, sold in Sony E, Canon RF, Nikon Z, Fuji X and MFT mounts. It squeezes a 1.33x anamorphic image onto the sensor, so footage gets the wide 2.4:1 cinematic frame, oval bokeh and horizontal blue flares straight out of camera. The fast T1.8 aperture is unusual for an anamorphic at this width, which makes it more usable in low light than the slower anamorphics it competes with. It is a manual-focus, manual-aperture lens aimed at filmmakers and hybrid shooters who want the anamorphic look without renting cinema glass.

Best forFilmmakers chasing the anamorphic look on a budgetWide establishing shots and gimbal workLow-light and night shootingHybrid shooters who also want stills with oval bokeh
Pros
  • 1.33x squeeze gives a 2.4:1 frame without cropping much resolution
  • Fast T1.8 aperture for an anamorphic wide
  • Wide 20mm keeps more in frame on Super 35 and full-frame bodies
  • Available in Sony E, Canon RF, Nikon Z, Fuji X and MFT mounts
  • Solid all-metal build with geared focus and aperture rings
  • Blue horizontal flares and oval bokeh out of camera
Cons
  • Manual focus and manual aperture only, no autofocus or electronics
  • Heavy and front-heavy; needs support on small gimbals
  • Noticeable distortion and soft corners wide open
  • Focus breathing and some chromatic aberration in high-contrast edges
  • Full-frame bodies need a 1.33x desqueeze in post or a monitor

What reviewers say

Filmmakers rate it as one of the most accessible ways to shoot true anamorphic, praising the fast aperture, the flares and the build for the money. Complaints centre on weight, softness wide open and the manual workflow.

What people mention
  • AperturePraisedOwners say the T1.8 opening lets them shoot interiors and night scenes that slower anamorphics can't handle.
  • Anamorphic lookPraisedReviewers like the oval bokeh and horizontal blue flares straight from the lens.
  • WeightCriticisedMany find it heavy and front-heavy, needing rigs or support on small gimbals.
  • SharpnessMixedIt is sharp in the centre but corners soften and distortion appears wide open.
  • Manual focusMixedThe geared focus ring is smooth, but the lack of autofocus and electronics slows run-and-gun work.
  • BuildPraisedThe all-metal body and damped rings feel sturdier than the price suggests.

Questions and answers

Does it cover a full-frame sensor?
It covers full-frame in some mounts but with heavy vignetting and distortion at the edges. Most shooters use it on Super 35 or APS-C, or crop in post.
How do I get the widescreen frame?
The 1.33x squeeze has to be desqueezed in post or on a monitor with anamorphic support. That gives roughly a 2.4:1 frame from a 16:9 sensor.
Is there autofocus?
No. Focus and aperture are fully manual, and the lens has no electronic contacts, so focus aids and camera metadata are limited.
Which mounts are available?
It comes in Sony E, Canon RF, Nikon Z, Fuji X and Micro Four Thirds mounts. Check the mount before ordering.
Is it good for stills?
Yes, if you want oval bokeh and flares in photos. You will need to desqueeze the images and focus manually.
What is in the box?
The lens, front and rear caps and a case. A support bracket or lens support is not included and is worth adding for gimbal work.
