Description

The ARRI ALEXA Plus High Speed shares ALEXAs image performance, simplicity of operation, reliability in extreme environments and versatility of workflow of the original ALEXA EV with integrated wireless remote control, the ARRI Lens Data System (LDS), additional outputs, lens synchronization for 3D, and built-in position and motion sensors
The lens mount of the Plus model incorporates LDS contacts, allowing lens data and depth of field to be displayed in the viewfinder or on monitors, and making speed/iris ramps easier. Lens metadata can be recorded using ProRes, HD-SDI or ARRIRAW. An advanced electronics side cover permits real-time wired or wireless remote control of camera REC/STOP and lens functions like focus and aperture, using either ARRI hand controllers such as the Wireless Compact Unit (WCU-3) or ccmotions modular evolution system.

Pair the ARRI ALEXA Plus high speed with our ARRI WCU for the ultimate control. Use on jibs, underwater housings, and camera car. All our ALEXAs have high speed licenses for recording up to 120 frames per second.

FiltersPermanent filters in front of the sensor: optical low pass, UV, IR. Includes a built-in Internal Filter Module (IFM-1) filter holder that accepts one of eight Full Spectrum Neutral Density (FSND) filters through manual insertion/removal.
Exposure Latitude14+ stops for all sensitivity settings from EI 160 to EI 3200, as measured with the ARRI Dynamic Range Test Chart (DRTC).
Exposure IndexEI 160: +5.2/-9.3

EI 400: +6.6/-7.9

EI 800: +7.8/-6.7

EI 1600: +8.6/-5.9
