||35 format film-style digital camera with an electronic viewfinder, a 16:9 active sensor area, integrated shoulder arch and receptacles for 15 mm lightweight rods
||35 format ALEV III CMOS sensor with Bayer pattern color filter array.
2880 x 1620 for ARRIRAW, 2880 x 1620 down sampled to 1920 x 1080 for HD video, ProRes and DNxHD, 2048 x 1152 for ProRes 2K
||Regular or High Speed mode. High Speed mode requires license purchase. Switching takes approx. 20 seconds.
0.75 - 60 fps
All speeds adjustable with 1/1000 fps precision. To record above 60 fps, the camera needs to be switched to high speed mode. Some limitations based on recording media or recording format apply.
Note: some limitations based on recording media or recording file settings apply.
||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.
||Permanent filters in front of the sensor: optical low pass, UV, IR. The lens mount can be upgraded to accept ARRI Full Spectrum Neutral Density (FSND) filters.
||14+ stops for all sensitivity settings from EI 160 to EI 3200, as measured with the ARRI Dynamic Range Test Chart (DRTC).
||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
||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.
||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'.
||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.
||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.

||For importing and storing ARRI Look Files, camera set up files, frame line files, feature license keys and user pixel masks. Stores frame grabs 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).
||(1) When REC OUT is set to 'ARRIRAW', frame grabs are only possible in the .ari format. Frame grabs are not possible during High Speed, 16:9 2K or when the option 'REC OUT = MON OUT Clone' is chosen.
||Note:Technical data based on Software Update Packet SUP 11.0 (ALEXA Classic).
