|Operating Modes||Regular or High-Speed mode. High-Speed mode requires license purchase. Switching takes approx. 40 seconds.|
|Frame Rates 16:9||ARRIRAW 0.75 – 60 fps
ProRes HD 0.75 – 120 fps
ProRes 2K 0.75 – 60 fps
DNxHD HD 0.75 – 120 fps
All speeds adjustable with 1/1000 fps precision. To record above 60 fps, the camera needs to be switched to high-speed mode (optional license).
|Shutter||Electronic rolling shutter, 5.0º – 358.0º up to 60 fps; 5.0° to 356° above 60 fps. Shutter angle adjustable with 1/10 degree precision.|
|Filters||Permanent filters in front of the sensor: optical low pass, UV, IR|
|Exposure Latitude||14+ stops for all sensitivity settings from EI 160 to EI 3200, as measured with the ARRI Dynamic Range Test Chart (DRTC).
For a graphic of how the exposure latitude shifts at different EIs, click here
|Exposure Index||Values behind the exposure index are the number of stops above and below 18% grey. These values are for Log C. Rec 709 and DCI P3 are the same except for 0.5 stops fewer in the low end at EI 160, 0.4 stops fewer in the low end at EI 200 and 0.2 stops fewer in the low end at EI 400.|
|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, colour 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 d(A) while recording ProRes @ 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 draws for camera and EVF-1 in typical use recording ProRes at 24 fps to a SxS PRO card at room temperature, without accessories. Initial power draws 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.|

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.|
