Camera Type 35 format film-style digital camera with integrated shoulder
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
Electronic rolling shutter, adjustable from 5.0° to 358.0° with 1/10 degree
Exposure Latitude 14 stops for all sensitivity settings from EI 160 to EI 3200, as measured with the ARRI Dynamic Range Test Chart (DRTC)
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 presets of 3200 (tungsten), 4300 (fluorescent), 5600 (daylight), 7000 (daylight cool). Green/magenta: -8 to +8 color correction (CC), 1 CC = 035 Kodak CC values or 1/8 Rosco values.
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.
Power Out 12V connector: limited to 12 V, up to 2.2A. RS, EXT and ETHERNET: input below 24V is regulated up to 24V, above 24V: input = output voltage. Both RS and EXT connectors combined: up to 2.2A. ETHERNET: up to 1.2A. Maximum power draw is also limited by the power source.
Lens Mount ARRI Exchangeable Lens Mount (ELM); ships with Lens Adapter PL Mount w/o LDS (LA-PL-1), 54 mm stainless steel PL mount, Super 35 centered
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
In-camera Recording Apple QuickTime/ProRes 4444, 422 (HQ), 422, 422 (LT) or 422 (Proxy) 1080p .mov files with embedded audio, timecode and metadata, recording to SxS PRO cards. ProRes 4444 is RGB 12 bit, all others YCbCr 10 bit; all legal range. Minimum recording times on a 32 GB card at 24 fps: ProRes 4444 – 15 minutes, ProRes 422 (HQ) – 19 minutes
Recording Outputs 2x REC OUT BNC connectors for uncompressed ARRIRAW or uncompressed HD-SDI video. Both with embedded audio, timecode and metadata.
Monitor Output 1x MON OUT BNC connector for uncompressed HD-SDI video: 1920 x 1080, 4:2:2 YCbCr; all legal range.
Color Processing For EVF-1, ProRes, REC OUT and MON OUT: Log C (film matrix off), Log C (film matrix on), Rec 709 or DCI P3. For Rec 709 and DCI P3 a customized look can be applied with ARRI XML Look Files.
Playback QuickTime clips can be played back from the SxS PRO cards to the EVF-1, MON OUT and REC OUT outputs. Playback audio is available embedded on MON OUT and REC OUT and on the headphones jack.
Processing Audio 16 bit linear internal image processing
SD Card For importing ARRI Look Files, camera set up files, log files, frame line files and feature licenses. Stores captured stills in ARRIRAW (.ari, 12 bit), TIFF (.tif, 16 bit), DPX (.dpx, 10 bit) and JPEG (.jpg, 8 bit) format. Also used for software updates.
Upgrades The Storage Interface Module (currently available for SxS PRO cards) can be exchanged for future storage modules. The Electronics Interface Module (available as either regular ALEXA or ALEXA Plus versions) can be exchanged for future control electronics. Exchangeable Lens Mount (ELM) allows other lenses beyond PL mount lenses to be used. Simple camera software updates. Licenses available for purchase: Anamorphic de-squeeze.
