Product description

• ALEXA SXT Plus Camera Body (LDS PL) The most versatile of the ALEXA SXT digital cinema cameras, the ARRI ALEXA SXT Plus Camera Body (LDS PL) features built-in, wireless camera and lens control, tilt and roll sensors, a fourth monitor-out port, and a third RS/accessory connector. Wireless lens and camera control is increasingly popular, and the SXT Plus saves time on set by enabling you to plug lens motors directly into the camera, no motor control box is needed.The SXT Plus is compatible with ARRI controllers like the WCU-4, as well as with the cmotion hand units. The integrated wireless control also eliminates the weight of a motor controller from your camera rig. The built-in tilt and roll sensors are viewed as an electronic horizon in the EVF by the operator, and the information is stored in your recording metadata for VFX and shot-matching uses.Record in UHD 4K, Cine 4K, 2K, or HD with 16-bit processing for sharp, natural-looking images. The ALEXA SXT Plus provides 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 Plus' Wide Color Gamut exceeds current display standards, and is compatible with the Rec 2020 color space. Full-image frame rates up to 120 fps enable capture for higher-clarity HFR (High Frame Rate) projects.The ALEXA SXT Plus' 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 Plus' outputs (EVF and four monitor outs), enabling the director, DP, DIT, or AC 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.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 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 Plus' maximum frame rates. RAID 1 (mirroring) capture provides additional data security for ALEXA SXT ProRes files.The ARRI LDS (lens data system), the IFM-1 filter holder, shoulder mount, and 15mm LWS rod support are built into the ALEXA SXT Plus. 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 Plus 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 compatible with the Rec 2020 color space.
    • Record up to 120 fps for compatibility with HFR (High Frame Rate) display outputs.

  Anamorphic Solutions

  • • The ALEXA's tall sensor is sized almost 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.
