Our take on the Sirui Venus 50mm T2.9 1.6x Full-Frame Anamorphic Lens

The Sirui Venus 50mm T2.9 is a full-frame anamorphic prime that squeezes a 1.6x image onto a standard sensor, giving widescreen framing and oval bokeh without a dedicated anamorphic camera. It is one of the few affordable 1.6x full-frame options, and it competes with Sirui's own 35mm and 75mm Venus lenses and pricier anamorphics from Cooke and Atlas. Reviewers like the compact build, the focus and iris gears, and the character of the flares; some note the lens is soft wide open and that the 1.6x squeeze needs care when desqueezing. It suits indie filmmakers and owner-operators who want anamorphic look on a full-frame mirrorless body.

Pros
  • 1.6x squeeze gives a wide anamorphic frame on full-frame sensors
  • Compact and light for an anamorphic prime
  • Geared focus and iris rings for follow focus and motors
  • Consistent with the rest of the Venus line for matched sets
  • Solid metal build at a fraction of high-end anamorphic cost
Cons
  • Soft wide open at T2.9; sharpens noticeably stopped down
  • Visible distortion and strong field curvature at the edges
  • Focus breathing and some chromatic aberration in high-contrast shots
  • No electronic contacts, so no EXIF or camera-driven iris

Questions and answers

Does the 1.6x squeeze work on a full-frame camera?
Yes. The Venus 50mm covers full frame and its 1.6x squeeze produces a widescreen image when desqueezed in camera or in post. You need a monitor or workflow that supports 1.6x desqueeze.
Is it parfocal or does it breathe?
It is not parfocal, and reviewers report noticeable focus breathing. Plan on pulling focus by monitor rather than relying on deep-focus shots.
Does it have electronic contacts?
No. It is a fully manual lens with geared focus and iris rings, so aperture and focus are set by hand and no EXIF is recorded.
How does it compare with the 35mm and 75mm Venus lenses?
All three share the 1.6x squeeze and geared manual design, so they cut together as a set. The 50mm sits between the wider 35mm and the tighter 75mm for a natural mid focal length.
What mount options are available?
Sirui sells the Venus line in several mirrorless mounts, including Sony E, Canon RF, Nikon Z and Leica L. Check that the mount matches your camera before ordering.
Is it sharp enough for 4K delivery?
Stopped down to around T4 it is usable for 4K, but wide open it is soft with low contrast. Many owners embrace that look rather than fight it.
