Product description

• ALEXA SXT EV Camera Body (LDS PL) Expanding upon the original ALEXA digital cinema camera, the ARRI ALEXA SXT EV Camera Body (LDS PL) records in UHD 4K, Cine 4K, 2K, and HD with 16-bit processing for sharp, natural-looking images. The versatile ALEXA SXT EV delivers an array of recording format choices in ARRIRAW and ProRes including 6:5 and 8:9 anamorphic modes (with SUP 3.0). With a base sensitivity of EI 800 and a dynamic range of 14 plus stops, your footage is effectively future-proofed for compatibility with HDR displays. The ALEXA SXT EV's Wide Color Gamut exceeds current display standards and is compatible with the Rec 2020 color space. Full-image frame rates of up to 120 fps enable capture for higher-clarity HFR (high frame rate) projects.The ALEXA SXT EV's improved image-processing system includes the ability to "bake-in" 3D LUTs at capture, a mild noise reduction feature (ANR), and a pixel correction function. ARRIRAW recording is optimized for VFX and archival capture, with uncompressed data available for sculpting with today and tomorrow's latest post-production processing. The look management architecture has been updated with the new ARRI Color Tool (ACT) and ARRI Look File (ALF-2), offering the ability to maintain your look from prep to post with on-set grading. Look files are stored in your recordings' metadata, enabling the automatic application of your on-set look to dailies, proxies, and editing files using popular NLE systems.User-friendly features include the ability to apply customized settings to each of the ALEXA SXT EV's outputs (EVF and three monitor outs), enabling the director, DP, DIT, or A.C. to see just the on-screen information they need, in SDR or HDR, in the color space of their choice. Standard and high-speed recording rates are now accessible in the same mode, eliminating the need to switch to a high-speed mode. Multiple control options include the right-side 3" LCD display, a condensed operator-side (left) interface, Ethernet-based browser control, and compatibility with the optional RCU-4 or WCU-4 control units.The modular ALEXA SXT family includes the flexibility of recording to the current or future media of your choice for each of your projects. Capture options include XR, and SXR capture drives with write speeds of up to 20 Gb/s, SxS PRO and SxS PRO+ cards, and CFast 2.0 cards. Faster in-camera processing speeds and capture to SXR drives boost the ALEXA SXT EV's maximum frame rates. RAID 1 (mirroring) capture provides additional data security for ALEXA SXT ProRes files.The ARRI LDS (lens data system) PL mount, the IFM-1 filter holder, shoulder mount, and 15mm LWS rod support are integrated into the ALEXA SXT EV. A 5-pin XLR connector supports 2-channel, 24-bit, 48 kHz audio. Choose from separately available Gold or V-mount battery plates, or an AC power supply to power the camera. Note: An EVF, ND filters, and recording-media adapter are not included with the SXT EV body, and must be ordered separately.

  Excellent Image Quality & High Dynamic Range

  • • The ALEXA SXT family combines the powerful image processing of the ALEXA 65 with the familiar design of the original ALEXA user interface, producing sharp, natural-looking footage.
    • A base sensitivity of EI 800 with a dynamic range of 14 plus stops effectively future-proofs your output for compatibility with HDR displays.
    • The ALEXA SXT records in a WCG (Wide Color Gamut) exceeding current displays, and is compatible with the Rec 2020 color space.
    • Record up to 120 fps for compatibility with HFR (high frame rate) display outputs.

  Wide Array of Recording Formats

  • • Choose from 14 in-camera recording formats, all of which are available in both full-fledged ARRIRAW, and smaller file ProRes options.
    • Format options include 16:9 ProRes UHD 4K, Open Gate ProRes 4K Cine, economical 6:5 ProRes 2K Anamorphic and 6:5 ProRes 4K Cine Anamorphic, the VFX-friendly 4:3 ProRes 2.8K, the high-res Open Gate ProRes 3.4K, and the versatile 16:9 ARRIRAW 3.2K.

  Anamorphic Solutions

  • • The ALEXA's tall sensor is sized almost exactly the same as 35mm film, enabling anamorphic lenses to maintain their native fields of view.
    • The ALEXA SXT'S efficient 6:5 sensor mode is equivalent to 1.194:1 image area, the same as half of the classic 2.39:1 CinemaScope aspect ratio. Use this mode to capture only the image area needed for a 2.39 output, with higher frame rates, higher ProRes resolutions, and fewer steps in post than the earlier 4:3 mode.
    • ALF-2 files are stored in your recording's metadata, enabling your dailies and proxy editing files to display the same look as your master files. Supported systems include DaVinci Resolve, Colorfront OSD, Codex Production Suite, Pomfort Silverstack, and Filmlight Daylight.

  Consistent Look Management

  • • A new ARRI Color Tool (ACT) and ARRI Look File (ALF-2) enable you to create new looks in-camera. For easy multi-camera coordination, these looks are compatible with ALEXA Mini and AMIRA cameras.
    • Lock in your look on set with the ALEXA SXT's live, on-set grading in Rec 709 or Rec 2020. Compatible third-party systems include Pomfort LiveGrade, Codex Live, Colorfront On-Set Live, Filmlight Prelight, Technicolor DP Lights, and more.
    • The same look management can be automatically applied when using NLE systems such as Avid Media Composer, Apple Final Cut Pro X, and Adobe Premiere Pro.
