Lens Overview — ARRI 47mm T1.8

The ARRI Signature Prime 47mm is a manual-focus cinema prime lens built for professional film and video production. Mounted on the industry-standard PL Mount, it is designed to pair with a wide range of cinema cameras that accept this fitting. With a maximum aperture of T1.8, this lens is well-suited for shooting in lower light environments and for achieving a shallow depth of field that helps separate subjects from their backgrounds.

Its 47mm focal length places it firmly in the standard range, making it a versatile choice for a broad variety of shooting scenarios — from dialogue-driven scenes to documentary and narrative work. The lens is rated for full-frame sensor coverage, meaning it can be used with modern large-format and full-frame cinema camera bodies without vignetting concerns. Weighing in at 1.81 kg, this is a substantial piece of glass, consistent with professional cinema lens construction.

Focus is entirely manual, which is standard practice on professional cinema sets where a dedicated focus puller manages focus pulls with precision. There is no image stabilization, which is expected in the cinema lens category where stabilization is typically handled at the rig or camera level. The Imperial Measurements variant of this lens features focus and iris markings calibrated in imperial units, making it a practical choice for crews working in feet-based production environments.

Key Features — ARRI 47mm T1.8

T1.8 Maximum Aperture: A fast T1.8 stop allows shooting in low-light environments and enables a shallow depth of field for strong subject separation.

47mm Standard Focal Length: Places the lens in the standard range, making it well-suited for dialogue scenes, documentary work, and general narrative production.

LPL and PL Mount: Ships with a PL mount; ARRI Signature Primes are also available with the LPL mount, offering compatibility with a wide range of professional cinema camera systems.

Large-Format Coverage: Covers ARRI's LF large-format sensor and full-frame sensors without vignetting, future-proofing the lens for modern large-format cinema platforms.

Imperial Focus Markings: Focus and iris scales are calibrated in feet, making this variant the practical choice for crews operating in imperial-unit production environments.

Manual Focus Design: Smooth, precise manual focus ring built for repeatable focus pulls by a dedicated focus puller on professional cinema sets.
