Extremely low distortion

and uniform image quality from corner to corner

ARRI Ultra Wide Zoom UWZ 9.5-18/T2.9 is the newest super wide-andgle zoom lens that will accomodate the next generation of large-sensor digital cameras thanks to image circle of 34.5 mm.

For maximum flexibility and efficiency on set, the ARRI Ultra Wide Zoom can easily replace a complete range of wide-angle primes. Equipped with the ARRI Lens Data System (LDS) this lens is optimized for VFX applications, thanks to precise lens metadata for zoom, focus and aperture settings.


  • Future-proof image circle of 34.5 mm for large sensor cameras
  • Very low image distortion, even at 9.5 mm
  • Virtually no image breathing
  • Uniform field illumination, even at close focus
  • Very high resolution and contrast up to the image corners
  • Fixed entrance pupil position over the entire zoom range
  • LDS for lens metadata in VFX applications
  • Exchangeable matte box interfaces
  • Matches other ARRI/FUJINON and ARRI/ZEISS lenses
  • ARRI LDS-PL or Canon EF mount

(2) Close Focus
Close focus is measured from the film/sensor plane.
(3) Magnification ratio
Magnification Ratio is the relationship of the size of an object on the film/sensor plane (first number) to the size of that object in real life (second number) at the close focus setting; horizontal (H) and vertical (V).
(4) Length
Length is measured from the lens mount to the front of the lens housing.
(5) Length including flange focal distance
Length is measured from the image to the front of the lens housing.
(6) Front Diameter
Diameter of the lens/matte box interface.
(7) Entrance Pupil
The distance from the entrance pupil to the film/sensor plane at focus = infinity. Positive numbers indicated an entrance pupil in front, negative numbers indicated an entrance pupil behind the film/sensor plane. The entrance pupil (often mistakenly called “nodal point”) is the center of perspective; moving the camera/lens system around the center of the entrance pupil prevents parallax errors. While largerly irrelevant for live action, this measurement is important for special effects work.
