The ALEXA M is a flexible solution consisting of a separate camera head
and body; it is tailored for action and aerial photography, tight corner
shots and 3D productions. The M
model features the same sensor, image processing, build quality,
efficient workflows and exceptional image quality that have made ALEXA
such a worldwide success. The head and body of the M are connected with a
fiber optic cable, which in a hybrid form can also be used for powering
the head. Weighing well under 3 kg, the compact front end offers
multiple mounting points and versatile maneuverability. Meanwhile the
body provides various options for recording images, sound and metadata,
accommodating as many different workflows as the standard ALEXA

General
Camera Type
35 format film-style digital camera with separate camera head and body.
Photosites
16:9 sensor mode:
2880 x 1620 for ARRIRAW, 2880 x 1620 down sampled to 1920 x 1080 for HD video, ProRes and DNxHD
4:3 sensor mode:
2880 x 2160 for ARRIRAW, 2880 x 2160 down sampled to 1440 x 1080 (pillar box) for monitoring in EVF-1 and HD video (MON OUT only)
Operating Modes
16:9 or 4:3 sensor mode. 4:3 mode is currently only available for ARRIRAW. Regular (max. 60 fps) or High Speed mode (max. 120 fps).
14 stops for all sensitivity settings from EI 160 to EI 3200, as measured with the ARRI Dynamic Range Test Chart (DRTC)
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
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) @ 24 fps and ≤ +30° Celsius (≤ +86° Fahrenheit) with lens attached, measured 1 m/3 feet in front of the lens.
Power In
Three inputs at the camera body: BAT connector, battery adapter back and battery adapter top. All accept 10.5 to 34 V DC. 85 W power draw for body in typical use recording to SxS PRO cards, without accessories. 40W power draw for head in typical use without accessories. A minimum of 15V power input to the body is required to power the camera head from the body through a standard SMPTE 311M hybrid fiber cable up to 50 meters, without accessories. The camera head has one 10.5 to 34 V DC power input that can be used to power the head independently from the camera body.
Power Out
Several outputs at the camera body: 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 = output voltage. Both RS and EXT connectors combined: up to 2.2 A. ETHERNET: up to 1.2 A. Maximum power draw is also limited by the power source. The camera head offers two RS connectors and one ETHERNET connector, with the same specifics as on the camera body.
