Built around a large-format 4K version of the original ALEXA sensor, the ARRI ALEXA LF (LPL) camera in this Basic Camera 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 modes. 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 SXT LF offers an array of recording format choices in ARRIRAW and ProRes, recording to 1 or 2TB SXR capture drives, or SxS PRO+ 256GB cards. 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 150 fps produce smooth slow motion and enable capture for higher-clarity HFR (High Frame Rate) projects.
The wireless connectivity of the ALEXA SXT W is built into the ALEXA LF, providing Wi-Fi and compatibility with ARRI ECS lens/camera control systems. One WVR-1 receiver is included in this basic kit, offering wireless video transmission in a range up to 2000′. An internal filter holder can be used to insert one of eight Large Format Full Spectrum Neutral Density (LF FSND) filters (available separately). Additional ALEXA LF features include compatibility with existing ARRI Look files and workflow, clip playback in both ARRIRAW or ProRes, and 2-channel, 5-pin XLR audio input. This basic ALEXA LF set also includes SXR and SxS media adapters, the EVF-1 electronic viewfinder with a VMB-3 mounting bracket and cable, the CCH-1 center carrying handle, and an SD card for storing/loading LUTs, SUPs, etc.
Large Full-Frame Sensor with Three Operating Modes
Like the entire ALEXA line, the ALEXA LF combines high-resolution with an optimal pixel size for excellent image quality. The ALEXA LF offers a choice of recording in 4448 x 3096 Open Gate, 3840 x 2160 16:9, and 4448 x 1856 2.39:1 anamorphic.
Native 4K Recording with ALEXA Image Quality
The ALEXA LF records vivid, nuanced images with natural-looking skin tones in native 4K. Its colorimetry is compatible with HDR (High Dynamic Range) and WCG (Wide Color Gamut) workflows, providing a subtle, immersive look.
Array of Recording Choices
Recording rates (using SXR capture drives) range from 90 fps ARRIRAW to 40 fps ProRes 4444 XQ in LF Open Gate, 90 fps ARRIRAW to 60 fps ProRes 4444 XQ in LF 16:9, and 150 fps ARRIRAW to 60 fps ProRes 4444 XQ in LF 2.39:1 anamorphic. ARRIRAW and ProRes 444 XQ/4444/422 HQ/422 options are available in all three sensor modes.
Wide Exposure Latitude
A base sensitivity of ASA 800, reduced noise, and a dynamic range of 14+ dovetails with HDR workflows.
New LPL Lens Mount
The new LPL lens mount, designed specifically for large-format sensors, is integrated into the ALEXA LF. With its wider diameter and shorter flange focal depth than the original ARRI PL mount, LPL-mount lenses can be designed smaller and lighter than earlier large-format optics.
ARRI Signature Primes
ARRI now offers a range of 16 large-format, LPL-mount Signature Prime lenses, ranging from 12 to 280mm. These separately available lenses display natural skin tones, smooth bokeh, and an organically pleasing look. The Signature Primes feature ARRI’s quick and comprehensive LDS-2 lens metadata system, and are constructed with machined magnesium for durability and lighter weights.
Compatible with PL Lenses, ALEXA Accessories & Workflow Tools
The ALEXA LF camera works with existing ALEXA-compatible lenses, accessories, and workflows. Use your favorite existing ARRI Look files and software tools with the ALEXA LF. A separately available PL-to-LPL mount adapter attaches to any PL-mount lens, both Super 35 or full-frame. The ALEXA LF transmits data from LDS-2, LDS-1, or /i (Cooke) lens data systems.
Same Wireless Connectivity as the ALEXA SXT W
The ALEXA LF features the same integrated Wi-Fi and wireless video transmitter as the ALEXA SXT W, providing quick compatibility with the included WVR-1 wireless video receiver, as well as ARRI’s various ECS (electronic lens/camera control system) components. This built-in wireless system saves build time on set, reduces cable spaghetti, and saves weight on your camera rig.
