The ARRI Signature Prime 18mm T1.8 Cinema Lens with LPL-Mount is an ultra-wide spherical prime that covers Vista Vision sensors. Ultra-wide coverage takes in a full setting from a short distance, which suits establishing shots, tight interiors, and vehicle work where the camera cannot be moved back. A fast T1.8 aperture lets camera operators separate subjects from their backgrounds or get the most out of available lighting when filming in darker environments, and the lens closes to T22. It uses an LPL-Mount with manual focus. ARRI LDS-2 lens data passes through the mount, recording focus, iris, and zoom positions alongside the image. The focus barrel is available in either imperial or metric markings.
Key Features
Ultra-Wide Vista Vision Coverage
The lens covers Vista Vision sensors, projecting a 46 mm image circle. An ultra-wide field of view keeps interiors, vehicle mounts, and establishing shots workable from close in, where there is no room to move the camera back.
T1.8 Maximum Aperture
At T1.8 the lens separates subjects cleanly from their backgrounds and gets the most out of available lighting when filming in darker environments. It closes to T22.
Imperial or Metric Focus Scale
The lens ships with either an imperial or a metric focus barrel. The scale is fixed at purchase rather than switchable, so a rental order or a set build has to specify which one is needed.
ARRI LDS-2 Lens Data
LDS-2 reports focus, iris, and zoom positions at higher resolution and faster than the original system, carrying the data over the mount without separate LDS contacts. Post and VFX read those positions back rather than reconstructing them from the footage.
