Description — ARRI 40mm
The ARRI Master Prime 40mm is a professional cinema prime lens built for the demands of high-end film and video production. Fitted with a PL Mount, it integrates directly with the industry's most widely used cinema camera interface, ensuring a solid and repeatable connection on set. The lens covers the Super 35 format, aligning with the sensor size found in many of the most popular professional cinema cameras in use today.
At a 40mm focal length within the standard range, it offers a natural perspective well-suited to dialogue scenes, environmental coverage, and a wide range of narrative applications. The standout technical specification is the T1.3 maximum aperture, which allows cinematographers to work confidently in challenging lighting conditions while maintaining the ability to isolate subjects with a shallow depth of field. Focus is entirely manual, placing control firmly in the hands of the operator and focus puller — appropriate for the precise demands of scripted production.
The lens weighs 2.3 kg, which should be factored into rig and support planning. No image stabilization is included, consistent with its intended use on professional, stabilized production setups.
