Our take on the Sirui 135mm T2.9 1.8x Anamorphic Lens for Canon RF

The Sirui 135mm T2.9 is a manual-focus anamorphic prime for Canon RF bodies that squeezes a 1.8x image onto the sensor, giving widescreen framing and the oval bokeh and horizontal flares anamorphic shooters want. It is one of the few long anamorphic primes for mirrorless, so it reaches tighter shots that wider anamorphics cannot without cropping. The fast T2.9 aperture helps in low light, and the all-manual design means no autofocus and no electronic communication with the camera. It suits filmmakers and hybrid shooters building a matched Sirui anamorphic set, not photographers who want autofocus or run-and-gun speed.

Pros
  • 1.8x squeeze gives a wide 2.4:1-style frame from a 16:9 sensor
  • Long 135mm focal length for tight anamorphic shots without cropping
  • Fast T2.9 aperture for low light and shallow depth of field
  • Geared focus and aperture rings suit follow-focus rigs
  • Matches the look of Sirui's other 1.8x anamorphics
Cons
  • Manual focus only, with no autofocus or electronic iris
  • Heavy and long, so it needs support and a solid rig
  • Focus breathing and edge softness wide open are common in this class
  • No image stabilization or camera communication
  • Best results need a full-frame body or a speed booster on Super 35

What reviewers say

Owners of Sirui's 1.8x anamorphics describe a distinctive widescreen look with strong oval bokeh and blue horizontal flares at a price far below cinema-brand anamorphics. They accept the manual focus and weight as part of the format, but note softness wide open and the need for careful support.

What people mention
  • Anamorphic lookPraisedOwners like the wide framing, oval bokeh and horizontal flares that define the anamorphic style.
  • SharpnessMixedIt is soft wide open at the edges but improves noticeably stopped down.
  • WeightCriticisedThe lens is long and heavy, so it needs support and balances poorly on small rigs.
  • FocusMixedThe geared manual focus ring works with follow-focus, but nailing focus on moving subjects takes practice.
  • BuildPraisedBuyers find the metal body solid and consistent with the rest of the Sirui anamorphic line.

Questions and answers

Does this lens autofocus on Canon RF?
No. It is fully manual, with no autofocus and no electronic communication, so you focus by hand and set aperture on the ring.
What sensor does the 1.8x squeeze need?
It is designed for full-frame RF bodies; on Super 35 you get a tighter crop, and a speed booster is not applicable on RF. A 16:9 full-frame frame becomes roughly 2.4:1.
Is it good for photography?
It can be used for stills, but manual focus, weight and the anamorphic desqueeze workflow make it a filmmaker's tool first.
How does it compare with Sirui's wider anamorphics?
It shares the 1.8x squeeze and look but gives a much tighter field of view, so it complements the 35mm and 50mm rather than replacing them.
Does it cover full frame?
Yes, it is built for full-frame coverage with the 1.8x squeeze, and it vignettes less on full frame than on smaller sensors.
What is in the box?
The lens comes with front and rear caps; check the listing for a case or support foot, since bundles vary.
Where is the Sirui 135mm T2.9 1.8x Anamorphic Lens for Canon RF cheapest?
At Adorama, for $499.00, as of our latest check.
