Description — ARRI 15.5-45mm T2.8 LDS PL
The ARRI Alura 15.5-45mm T2.8 LDS is a PL-mount wide-angle zoom lens designed for Super 35 format cinema cameras. It spans a focal length range of 15.5mm to 45mm, classified as a wide-angle zoom, and maintains a constant maximum aperture of T2.8 throughout that range — a critical advantage for consistent exposure management during zoom moves. The lens is manual focus only, with no autofocus system, placing creative focus control entirely in the hands of the camera operator or focus puller.
The LDS (Lens Data System) designation on the PL mount enables electronic communication of lens metadata to compatible camera bodies and follow focus systems, supporting sophisticated focus tracking and data logging in professional cinema workflows. With a weight of 2.2kg, the lens is built for professional cinema rigs rather than lightweight mirrorless setups. No image stabilization is included, consistent with the lens's intended deployment on stabilized production equipment. The Cinema / Video camera system classification confirms this lens is purpose-designed for the demands of professional filmmaking.
