Lens Overview — ARRI 18mm

The ARRI Master Prime 18mm is a wide-angle prime lens built for cinema and video production, designed around the Super 35 format and featuring a PL Mount for compatibility with professional cinema camera systems. With a maximum aperture of T1.3, this lens offers significant light-gathering capability, enabling cinematographers to work in lower-light conditions and achieve a shallow depth of field when needed. Weighing in at 2.22kg, the lens has a solid, professional-grade build that is well-suited to high-end production environments.

As a manual focus lens with no autofocus or image stabilization, it is intended for use with dedicated focus-pulling workflows typical of cinema production. The focal length is fixed at 18mm, placing it firmly in wide-angle territory and making it a strong choice for environmental shots, tight interior spaces, or any scenario where a broad field of view is required. The lens mounts via PL Mount, the standard interface across a wide range of professional cinema cameras.

With no filter thread size specified, users should verify front-end accessories independently. Overall, this is a purpose-built cinema prime aimed squarely at professional narrative and commercial production workflows demanding maximum optical performance at a fast aperture.
