14+ stops for all sensitivity settings from EI 160 to EI 3200, as measured with the ARRI Dynamic Range Test Chart (DRTC). |
Exposure Index |
|
White Balance |
Presets for 3200 (tungsten), 4300 (fluorescent), 5600 (daylight) and 7000 (daylight cool). Automatic calculation or manual white balance for 2000 to 11000 Kelvin, adjustable in 100 K steps |
Color Correction |
While white balance changes the red/blue hue of the image, color correction changes green/magenta. Adjustable range from -12 to +12 CC. 1 CC corresponds to 035 Kodak CC values or 1/8 Rosco values. |
Sound Level |
Under 20 db(A) while recording ProRes 4444 16:9 HD @ 24 fps and ≤ +30° Celsius (≤ +86° Fahrenheit) with lens attached and fan mode set to 'Regular', measured 1 m/3 feet in front of the lens. Silent operation at higher temperatures possible with fan mode set to 'Rec low'. |
Power In |
Three possible inputs: BAT connector, optional battery adapter back or optional battery adapter top. All inputs accept 10.5 to 34 V DC. Approx. 85 W power draw for camera and EVF-1 in typical use recording ProRes at 24 fps to an SxS PRO card at room temperature, without accessories. Initial power draw during power up is higher. |
Power Out |
12 V connector: limited to 12 V, up to 2.2 A. RS, EXT and ETHERNET: input below 24 V is regulated up to 24 V; above 24 V: input voltage = output voltage. RS and EXT connectors combined are limited to 2.2 A. ETHERNET is limited to 1.2 A. Maximum power draw is also limited by the power source. |
Weight |
ALEXA body with SxS Module: 6.3 Kg/13.8 lbs. |
Dimensions |
Length: 332 mm/12.95”, width: 153 mm/6.02”, height: 158 mm/6.22”. |
Environmental |
-20° C to +45° C (-4° F to +113° F) @ 95% humidity max, non-condensing. Splash and dust proof through sealed electronics. System cooling through radiator/single fan. |
Lens Mount |
54 mm stainless steel PL mount, Super 35 centered. 52.00 mm nominal flange focal depth. |
Viewfinder |
Low latency (≤1 frame delay) electronic color viewfinder ARRI EVF-1 with 1280 x 784 F-LCOS micro display (image: 1280 x 720, status bars: 1280 x 32 above and 1280 x 32 below image) and ARRI LED illumination, both temperature controlled. Image can be flipped for use of viewfinder on camera left or right. Viewfinder Mounting Bracket allows movement of viewfinder forward/backwards, left/right, up/down, 360 degree rotation and placement on camera left or right. EVF-1 controls: viewfinder and basic camera settings, ZOOM button (2.25x magnification 'pixel to pixel'), EXP button (false color exposure check) and jog wheel. |
Assistive Displays |
For EVF-1 and MON OUT: preset and custom frame lines, user rectangles, surround view, 180º image rotation, camera status, false color exposure check, peaking focus check, compare stored image with live image, RETURN IN video and optional anamorphic de-squeeze (license key required). For MON OUT additionally: Reel & clip number. |
Control |
Camera right: Main user interface with a 3” transflective 400 x 240 pixel LCD color screen, illuminated buttons, button lock and jog wheel. Camera left: Operator interface with illuminated buttons and button lock. Optional accessory Remote Control Unit RCU-4 for cabled remote control via camera ETHERNET connector. Optional accessory Wireless Compact Unit WCU-4 for wireless remote control (UMC-3A or UMC-4 required). |
In-camera Recording |
QuickTime/ProRes or MXF/DNxHD recording onto one or two (Dual Recording) SxS PRO or SxS PRO+ cards. All formats include embedded audio, timecode and metadata. |
Recording Outputs |
2x 1.5G or 3G REC OUT BNC connectors for ARRIRAW T-Link or HD-SDI video. Both with embedded audio, timecode, metadata and recording flag. |
Monitor Output |

Image Processing |
16 bit linear internal image processing in full ALEXA native color space. Target output color spaces for ProRes, DNxHD, REC OUT and MON OUT: Log C or Rec 709. For Rec 709, a customized look can be applied during record and playback with ARRI Look Files. Optional horizontal image mirroring. |
Synchronization |
Master/Slave mode for precision sync of settings, sensor, processing, HD-SDI outputs and QuickTime/ProRes or MXF/DNxHD recording for 3D applications. PHASE user button for shifting camera phase to move phase artifacts out of frame, i.e. when shooting a CRT monitor or rear screen projector (works in Rec Run TC mode). |
Playback |
Playback of ProRes or DNxHD from SxS PRO or SxS PRO+ cards visible on EVF-1, MON OUT and REC OUT. Playback audio available over headphone jack and embedded in the MON OUT and REC OUT signal. |
Audio |
1x XLR 5 pin AUDIO IN for 2 channel, line level, balanced audio. 24 bit/48 kHz A/D conversion. Uncompressed PCM audio recording to ARRIRAW, ProRes, DNxHD and embedded in all HD-SDI outputs. Only available with same project/sensor speed at 23.976, 24, 25, 29.97 and 30 fps. Max of 2.5 dBm output from AUDIO OUT headphones connector. |
Connectors |
2x slots for SxS PRO cards (SxS) |
SD Card |
For importing and storing ARRI Look Files, camera set up files, frame line files, feature license keys and user pixel masks. Stores captured stills from the REC OUT image path in ARRIRAW (.ari, 12 bit), TIFF (.tif, 16 bit), DPX (.dpx, 10 bit) or JPEG (.jpg, 8 bit) format (1). Stores log files. Also used for installing Software Update Packets (SUPs). |
Upgrades |
The Storage Interface Module (SxS Module) can be exchanged for future storage modules (i.e. XR Module). The Electronics Interface Module can be exchanged for future control electronics (i.e. Plus upgrade). Exchangeable Lens Mount (ELM) allows other lenses beyond PL mount lenses to be used. Simple camera software updates via free-of-charge Software Update Packets (SUPs) and payable license keys – Anamorphic De-squeeze, High Speed and DNxHD.
