Description
With its compact, lightweight carbon body, the ALEXA Mini Body with 4:3 and ARRIRAW complements the range of full-size ALEXA cameras, and is especially useful for capturing specialized shots. The self-contained ALEXA Mini can record UHD-resolution images with up to 14 stops of dynamic range. Its 35mm-sized CMOS sensor features a titanium mount and a 4:3 aspect ratio. The included 4:3 Open Gate, and ARRIRAW licenses enable ProRes recording in several widescreen options, as well as in-camera and external ARRIRAW capture. Use the preinstalled ARRI Look Library license to quickly apply any of 87 graded looks to your footage.
Operate the ALEXA Mini via wireless remote control, using the MVF-1 viewfinder, or while viewing an onboard monitor. Its small size suits it for use with gimbals, handheld rigs, or quadcopters and for multicamera shots, and in tight quarters. The lens mount is interchangeable, opening up a wider choice of lenses such as EF-mount still lenses. The ALEXA Mini can make use of ARRI AMIRA mounts, a boon for shooters working with both units.
Image quality, formats, and workflow are identical to those offered by other ALEXA models, enabling you to produce matching images across cameras, including in anamorphic mode. Record ProRes or ARRIRAW to an internal CFast card or externally to a Codex recorder (not included). Up to four ALEXA Minis can record simultaneously to one Codex recorder. The Mini’s maximum frame rate of 200 fps (ProRes) enables you to avoid adding a separate camera for high-speed work.
The ALEXA Mini’s integrated lens motor control is a space-saving feature useful when using gyro-stabilized and other specialized rigs, eliminating the need for an external control box. Integrated Wi-Fi connectivity enables the use of iOS or Android devices for remote control. Remote control is also possible using the ARRI WCU-4 hand unit. The ALEXA Mini offers high-quality performance in underwater locations and other low-light settings.
Built-in, motorized ND filters let you quickly respond to ambient light changes; this internal design also frees up a slot in your matte box for another filter. The ARRI LDS (lens data system) function is also built into the ALEXA Mini, enabling your AC to quickly adjust to changing parameters displayed on a control unit during a shot.
Using the power and large pixels of the 4:3 ALEV III sensor, the ALEXA Mini records up to UHD 4K ProRes images with the dynamic range, skin tones, and true-to-life colors for which ARRI cameras are noted. Recording in Open Gate and MFX/ARRIRAW formats requires additional, downloadable licenses (not included). Looking ahead to future standards, the wide dynamic range of the ALEXA Mini makes it suitable for HDR displays, and its 0.75-200 fps speed range can be used for increasingly-popular HFR (high frame rate) capture modes.

Power Consumption
⚡ ARRI Alexa Mini • Electrical & Power Profile
- Operating Voltage: 10.5V to 34V DC (8-pin LEMO input; natively compatible with both 14.4V V-Mount/Gold Mount batteries and 24V/26V cinema block batteries)
- Power Draw (Idle / Standby): ~45W to 55W
- Power Draw (Active Recording w/ MVF-1): ~84W (Official ARRI maximum rating for the camera body actively recording while powering the MVF-1 viewfinder)
- Internal Battery Standard: None (Relies entirely on external 14.4V or 24V/26V cinema battery blocks)
- External Supply Options: 8-pin LEMO power input via V-Mount / Gold Mount battery plate or 24V/26V block battery
⏱️ Estimated Operating Runtimes (84W Production Draw @ 85% Efficiency)
- 🔋 V-Mount 98Wh (14.4V): ~1.0 hour (59m)
- 🔋 V-Mount 150Wh (14.4V): ~1.5 hours (1h 31m)
- 🔋 V-Mount 190Wh (14.4V): ~1.9 hours (1h 55m)
- 🔋 Cine Block / V-Mount 290Wh: ~2.9 hours (2h 56m)
📊 Engineering Note: The 85% Efficiency Standard
- Usable Energy Derating: Published calculations apply a standard 0.85 multiplier (Usable Wh = Rated Wh × 0.85). Cinema cameras enforce an automated low-voltage threshold (~11.5V–12.0V on 14.4V systems) to preserve ARRIRAW / ProRes file-header closure and prevent media corruption. The remaining variance accounts for thermal dissipation in internal 24V step-up DC-DC conversion and cell impedance under high amperage loads.
⚠️ Production Advisory: ARRI notes that the Alexa Mini operates internally at 24V; powering 24V accessories via the EXT or RS ports from a 14.4V battery increases amperage draw. ARRI recommends a power source rated above 100W and advises powering on-board monitors directly from battery D-Tap ports rather than through the camera body.
