Lens Overview — ARRI 40mm

The ARRI Master Prime 40mm is a manual-focus prime lens built for cinema and video production, designed around the PL Mount standard and covering the Super 35 format. With a maximum aperture of T1.3, it sits firmly in the fast-prime category, giving cinematographers the ability to shoot in low-light conditions and achieve a shallow depth of field with greater creative control over subject separation. The 40mm focal length falls within the standard range, making it a versatile choice for a wide variety of shooting scenarios — from close-up character work to wider environmental shots that still retain subject intimacy.

Weighing in at 2.3 kg, the lens is a substantial but manageable piece of kit for professional cinema rigs. Focus is entirely manual, which is standard and expected for a lens of this class, ensuring the cinematographer and focus puller retain precise, deliberate control over every frame. The PL Mount provides a secure, industry-standard interface compatible with a broad range of professional cinema cameras.

Image stabilization is not present, which is consistent with a lens designed for use on stabilized rigs, gimbals, or supported camera setups common in professional production environments. This is a purpose-built tool for serious cinema work.
