Ultra Wide Zoom

The ARRI Ultra Wide Zoom UWZ 9.5-18/T2.9 is the first super wide-angle zoom lens for the professional cine market. With an unusually accommodating image circle of 34.5 mm, the UWZ has been designed for both existing and future generations of large-sensor digital cameras, incorporating patented, cutting-edge lens technologies that overcome known problems with previous wide-angle zooms. The optical performance of this telecentric design is comparable to, or even exceeds, that of high-end wide-angle prime lenses. For maximum flexibility and cost efficiency on set, the UWZ can easily replace a complete range of wide-angle primes.

Optimized for the requirements of VFX applications, the UWZ is ideal for plate shots or any other situation where maximum image quality is vital. Distortion is at a level of less than 1% at 9.5 mm and less than 0.1% at 18 mm, which means that straight lines stay straight, even at close focus. Due to a new multilayer, anti-reflective coating, flare and veiling glare are reduced to an absolute minimum. The near telecentric optical design means that the UWZ has a highly uniform field illumination, from the center to the very corners of the image. Built-in ARRI Lens Data System (LDS) functionality provides precise lens metadata for zoom, focus and aperture settings, smoothing postproduction workflows. 

Features

  • Future-proof image circle of 34.5 mm for large sensor cameras
  • Zoom index marker
  • Very low image distortion, even at 9.5 mm
  • Virtually no image breathing
  • Uniform field illumination, even at close focus
  • Fixed entrance pupil position over the entire zoom range
  • Built-in lens support
  • LDS for lens metadata in VFX applications
  • Exchangeable matte box interfaces (dia. 134 mm and 156 mm)
  • Matches other ARRI/FUJINON and ARRI/ZEISS lenses
  • Included in delivery: ARRI-PL-LDS and Canon EF mount

Ultra Wide Zoom Quote

The Ultra Wide Zoom is an incredible lens with superb qualities – so clean and with no distortion. I shot an entire project with the UWZ and it provided boundless storytelling possibilities.

(1) Lens Mount: Positive locking (PL) 54 mm stainless steel lens mount with Lens Data System (LDS) contacts.

(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.

Ultra Wide Zoom aerial shoot

The ARRI Ultra Wide Zoom UWZ 9.5-18/T2.9 is an exceptionally high-performing, distortion-free wide-angle zoom lens for the professional cine market. Cinematographer Bill Bennett, ASC, recently combined the UWZ with an ALEXA M on an aerial shoot in the skies above LA, using an MBB Bo 105 helicopter and Gyron gyro-stabilized mount from Wolfe Air Aviation.
