Technical Data

Camera Type 35 format film-style digital camera with integrated shoulder arch and receptacles for 15 mm lightweight rods.
Sensor 35 format ALEV III CMOS with Dual Gain Architecture (DGA) and Bayer pattern color filter array. 1.5x oversampling for 1920 x 1080 output. 1.78:1 (16:9) sensor area used for image out.
Frame Rates "ProRes 422 (Proxy), 422 (LT), 422 and 422 (HQ): 0.75 - 60 fps
Shutter Electronic rolling shutter, adjustable from 5.0° to 358.0° with 1/10 degree precision.
Exposure Latitude 14 stops for all sensitivity settings from EI 160 to EI 3200, as measured with the ARRI Dynamic Range Test Chart (DRTC)
Exposure Index EI 160 (+5.0 / -9.0), EI 200 (+5.3 / -8.7), EI 400 (+6.3 / -7.7), EI 800 (+7.4 / -6.6), EI 1600 (+8.4 / -5.6), EI3200 (+9.4 / -4.6)
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 have 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. Otherwise they are the same.
White Balance Separate red/blue and green/magenta balance available through Auto White Balance or manual setting. Red/blue: 2000 to 11000 Kelvin, adjustable in 100 K steps, with 1 CC = 035 Kodak CC values or 1/8 Rosco values. presets of 3200 (tungsten), 4300 (fluorescent), 5600 (daylight), 7000 (daylight cool). Green/magenta: -8 to +8 color correction (CC),
Sound Level Under 20 dB(A) at ≤ +30° Celsius (≤ +86° Fahrenheit) with lens attached and fan mode set to ‘Regular’, measured 1 m/3 feet from the image plane. Silent operation at higher temperatures possible with fan mode set to “Rec low’.
Power In Three inputs: BAT connector, battery adapter back and battery adapter top. All accept 10.5 to 34 V DC. 85 W power draw for camera and EVF-1 in typical use recording to SxS PRO cards, without accessories.
