The New Large-Format Camera System

ARRI introduces a complete large-format system that meets and exceeds modern production requirements, delivering unprecedented creative freedom. Based on a large-format 4K version of the ALEXA sensor, the system comprises the ALEXA LF camera, ARRI Signature Prime lenses, LPL lens mount and PL-to-LPL adapter. These system elements have been designed to take full advantage of the enlarged sensor, while also offering compatibility with existing lenses, accessories and workflows.

Large-format aesthetic with ALEXA image quality

Featuring a sensor slightly larger than full frame, ALEXA LF records native 4K with ARRI’s best overall image quality. This allows filmmakers to explore an immersive large-format aesthetic while retaining the sensor’s natural colorimetry, pleasing skin tones and stunning capability for HDR and WCG workflows. Versatile recording formats, including efficient ProRes and uncompressed, unencrypted ARRIRAW up to 150 fps, encompass all on-set workflow requirements.

Three sensor modes for limitless applications

ALEXA LF has the largest sensor of any full-frame cinema camera on the market. Maintaining the ALEXA family’s optimal pixel size for highest overall image quality results in a 4448 x 3096 picture, which can be recorded in full using the LF Open Gate mode. An LF 16:9 mode maximizes lens options while meeting 4K deliverable standards, and an LF 2.39:1 mode combines a cinematic widescreen image with high frame rates up to 150 fps for sensuous slow motion. All sensor modes offer true 800 ASA sensitivity as well as reduced noise, providing the perfect canvas for modern, subtle lighting techniques.

A larger mount for a larger format

A crucial element of this new system is the LPL lens mount, optimized for large-format sensors. A wider diameter and shorter flange focal depth allows the ARRI Signature Prime lenses and all future large-format optics to be small and lightweight, with a fast T-stop and pleasing bokeh—a combination of features that would not be possible within the confines of the PL lens mount. The LPL mount will also be available for other ARRI cameras such as the ALEXA Mini, and is being licensed to third-party lens and camera manufacturers.
