Arri Alexa Mini LF

ARRI ALEXA Mini LF LPL-Mount Overview

Built around a large-format 4K version of the original ALEXA sensor, the ARRI ALEXA Mini LF (LPL) camera in this Lens Mount Set offers native 4K recording in three sensor modes, with ARRIRAW or ProRes recording in LF Open Gate, LF 16:9, or LF 2.39:1 mode. The ALEXA LF combines large-format resolution with an optimal pixel size for excellent image quality producing vivid, nuanced images with natural skin tones and smooth bokeh. The ALEXA LF is designed with ARRI’s LPL lens mount that has been optimized for large-format capture and is compatible with all PL-mount lenses with the use of a PL-to-LPL adapter. A wider diameter and shorter flange focal depth than the original ARRI PL mount enable LPL-mount lenses to be smaller and lighter than earlier large-format optics.

The ALEXA Mini LF is a hybrid of the ALEXA Mini and the ALEXA LF, as it retains the same LF sensor but the form factor of the Mini. The new exterior has a left-side media bay with two rows of connectors on the back and a slot to insert 1TB Codex media. It also features six user buttons, three more than the Mini, to configure to your preference. It also features extra 12 and 24V power outputs and a black burst/tri-level input. The audio connector is now 6-pin, so it doesn’t conflict with the 5-pin timecode port.

The Mini LF offers an array of recording format choices in MXF ARRIRAW and MXF ProRes, recording to 1TB Codex capture drives. With a base sensitivity of EI 800, 16-bit processing, and a dynamic range of 14-plus stops, your footage is effectively future-proofed for compatibility with HDR displays. Frame rates up to 90 fps produce smooth slow motion and enable capture for higher-clarity HFR (High Frame Rate) projects.

An internal Large-Format Full-Spectrum Neutral Density (LF FSND) filter system features 0.6, 1.2, and 1.8 filters. Additional ALEXA Mini LF features include compatibility with existing ARRI Look files and workflow, clip playback in both MXF ARRIRAW or MXF ProRes, and 2-channel, 6-pin XLR audio input.

This Lens Mount Set includes the ALEXA Mini LF, the PL-to-LPL adapter, and the ARRI LPL lens mount so you can shoot with a variety of lenses on the ALEXA Mini LF.

The ARRI PL-to-LPL Lens Adapter enables you to attach a PL-mount lens to the ARRI ALEXA LF camera. Compatible with any PL-mount lens, Super 35 or full-frame, this adapter can be securely fastened to your lens without the use of tools.
