Arri Alura 18-80mm T2.6 Studio Zoom Lens

PL Mount Zoom Lens (Feet Scale)

ARRI and FUJINON have joined their extensive expertise to create a completely new family of modern cine zooms. Using the latest in optical design technology and innovative manufacturing techniques, the ARRI/FUJINON Alura Zooms combine the highest optical performance with an amazingly small size, weight and price. They are available as Studio zooms for use on a tripod or crane with a wider focal range, or as lightweight zooms which are significantly smaller and lighter in exchange for a reduced focal range.

Matched Zooms
Matched wide and long PL mount zooms for an efficient shooting pace, Small size and low weight for quick and easy handling on the set.

Fast and Steady
T2.6 Consistent aperture over entire zoom range.

Outstanding Optical Performance

• (1) Positive locking 54 mm stainless steel lens mount
• (2) Close focus is measured from the film/sensor plane
• (3) 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 and the telephoto zoom setting
• (4) Length is measured from the lens mount to the front of the lens housing
• (5) Diameter of the lens/matte box interface
• (6) The distance from the entrance pupil to the film/sensor plane. 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.
• (7) The image diameter (ID) is the diameter of the image circle needed for the respective format.
