Lens OverviewARRI 12mm T1.8

The ARRI Signature Prime 12mm is a wide-angle cinema lens built for full-frame and large-format sensor cameras. Mounted on the PL Mount, it offers broad compatibility across the cinema and video camera ecosystem. With a maximum aperture of T1.8, this prime lens delivers strong light-gathering capability, giving cinematographers meaningful control over exposure and depth of field in demanding shooting conditions.

As a manual focus lens with no autofocus or image stabilization, it is purpose-built for the controlled environment of professional film and television production, where focus pullers work with dedicated follow-focus systems. The lens covers the full-frame format, making it suitable for use with today's large-format cinema sensors. At 12mm, it sits firmly in wide-angle territory, useful for expansive establishing shots, environmental storytelling, and immersive perspectives.

Weighing in at 2.6kg, it carries the heft expected of a professional cinema prime, and is best suited to a rigged camera build rather than handheld run-and-gun work. The Signature Prime 12mm T1.8 is a dedicated tool for serious production work, offering a fixed focal length that demands intentional composition and precise operating technique.
