Description — ARRI 25mm T1.8
The ARRI Signature Prime 25mm T1.8 is a professional cinema prime lens designed for full-frame sensor coverage and built around the industry-standard PL Mount. With a maximum aperture of T1.8, it offers strong light-gathering capability, giving cinematographers the ability to work in challenging lighting conditions while maintaining the capacity for shallow, expressive depth of field. As a prime lens with a fixed 25mm focal length, it sits in wide-angle territory — a popular choice for environmental shots, intimate close work, and scenes requiring a sense of space and context.
Focus is fully manual, which is the standard operating mode on professional cinema productions where precision focus pulling is part of the workflow. The lens weighs 1.7kg, a figure that matters when configuring camera rigs for handheld, gimbal, or crane use. It carries no image stabilization, so it is best deployed with appropriate camera support.
Categorized as a Cine type lens within the Cinema / Video camera system, the Signature Prime 25mm T1.8 is purpose-built for the demands of high-end film and commercial production.
