ARRI ALEXA 265 — Large-Format Cinema Camera Overview

ARRI’s ALEXA 265 brings the signature 65 mm large-format look into a much smaller, more versatile body. Think
big-format presence, updated color science, a smarter ND cartridge system, and real production agility for gimbals,
remote heads, and fast builds—without abandoning the reliability DPs expect from ALEXA.


Overview & Positioning

  • Large-format imaging, smaller footprint: ALEXA 265 is ARRI’s new-gen 65 mm digital cinema camera, designed to deliver the immersive perspective and graceful focus roll-off of big format in a compact body.
  • Nimble deployment: Built for gimbals, cranes, remote heads, car rigs, and handheld work where older 65 mm systems were too bulky.
  • Modern pipeline: ARRIRAW capture with LogC4/REVEAL color science integrates cleanly with ACES/RCM workflows and HDR deliveries.
  • Real-world intent: A production tool for premium features, streamers, luxury/commercial work, VP/LED stages, and high-end docu spots.

Sensor & Image Pipeline

The ALEXA 265 uses a new 65 mm-class sensor that captures at a 6K+ “Open Gate” scale for maximum field of view and oversampling flexibility.
The practical effect: wider compositions without distortion, dimensional faces at moderate focal lengths, and exceptionally clean plates for VFX.

Why the format matters

  • Perspective & presence: Large format lets you go wider without “feeling wide,” preserving natural geometry on faces and spaces.
  • Micro-contrast & texture: ALEXA’s tonal separation + big photosites create that premium, “effortless” image density.
  • Post headroom: Oversampling yields tidy downscales for 4K HDR masters and resilient keys/comps.

Color Science & Workflow

The 265 runs ARRI’s modern REVEAL color science with LogC4, aligning it with contemporary ARRI pipelines
while preserving the hallmark ALEXA skin-tone fidelity and highlight behavior that colorists love.

  • ARRIRAW → ACES/RCM: Clean IDTs and viewing transforms for SDR/HDR monitoring and finishing.
  • Highlight strategy: Classic ALEXA-style roll-off—protect peaks on set, then shape mids and speculars gently in grade.
  • LUTs/Looks: Adopt LogC4-native LUTs; legacy ALEXA 65 looks won’t map 1:1 to the new pipeline.

Internal ND Cartridge System

A standout hardware feature is the filter cartridge door: single-stop ND cartridges slide directly in front of the sensor and are chip-encoded for
accurate metadata. The architecture is designed to accommodate future creative/diffusion options, reducing matte-box swaps and speeding up exposure control.

  • Speed: Fast, reliable ND swaps without disturbing the lens or matte box.
  • Metadata: ND values tag into clip info—consistent dailies and grade decisions.
  • Creative path: Potential for bespoke cartridges (diffusion/effects) in addition to neutral density.

Media, Storage & Data

The camera records ARRIRAW to Codex media with support for HDE (High Density Encoding) to shrink storage footprints while preserving image integrity.
On-set data moves are predictable and checksum-friendly—plan for robust near-set storage and dailies bandwidth.

  • ARRIRAW + HDE: Quality-first RAW with sensible data management.
  • Codex drives/readers: Proven reliability and tooling; well-supported across labs.
  • DIT pipeline: Familiar ARRI color + look management; painless conforms in Resolve/Baselight/Colorfront.

Monitoring, Outputs & Control

Dual 12G-SDI outputs enable parallel SDR/HDR monitoring paths. The MVF-2 viewfinder provides full camera control, and Ethernet-based control/metadata
hooks make the 265 friendly for virtual production and remote workflows.

  • SDI I/O: Independent monitor feeds for village and DIT.
  • HDR previews: Evaluate highlights/contrast without over-baking a show LUT.
  • Metadata/Remote: Camera Access Protocol support, wired/wireless controls, lens data, and show look transport.

Mounts, Power & Accessories

  • Mounts: Native LPL with adapters for PL/EF/Leitz M; designed to play nicely with modern lens ecosystems and ARRI ECS.
  • Power: 24 V-friendly architecture with regulated accessory rails; optional power distro modules simplify complex builds.
  • ECS integration: Built-in radio + LBUS lens control (Hi-5/WCU-4, etc.) for tidy, cable-light rigs.

Form Factor & Ergonomics

Compared to earlier 65 mm systems, the 265 is dramatically smaller and lighter, quiet in operation, and weather-resistant to common on-set conditions.
Translation: you can realistically fly large format on stabilized heads or shoulder it for specialty moves without blowing the day’s schedule.

  • Compact & rigid: Purpose-built chassis with smart antenna layout and I/O that won’t fight your rigging.
  • Low noise: Engineered thermals that behave on long takes and hot stages.
  • Set-tough: Sealing and finish choices aimed at real-world production wear.

Use Cases & Strengths

  • Premium narrative & episodic: Large-format presence with a practical on-set footprint.
  • Luxury/commercial: Faces, fabrics, metals, liquids—elevated with dimensional texture.
  • Second-unit/B-cam: Big-format match without bringing a crane truck for every setup.
  • Gimbal/remote head: Stabilized builds that previously balked at 65 mm weight.
  • VP/LED stages: Metadata-aware pipeline; flexible monitoring; predictable color.

Differences vs ALEXA 65 & Other Large-Format Options

Feature ALEXA 265 ALEXA 65 Other FF/LF Options
Body size/weight Significantly smaller, lighter, gimbal-friendly Much larger, studio-oriented Varies (some FF/LF lighter, smaller sensors)
Color pipeline REVEAL + LogC4 Legacy ALEXA65 pipeline Manufacturer-specific (ACES-friendly)
Internal NDs Cartridge system with metadata External filtration Some have internal NDs; implementation varies
Capture ARRIRAW + HDE on Codex ARRIRAW (older media) RAW/ProRes/X-OCN/REDCODE etc.
Use case fit Large-format everywhere, all day Large-format prestige, heavier builds Broad—from nimble FF to studio VV

Considerations & Limitations

  • Rental-only: Access and holds flow through ARRI Rental—plan your tests and dates early.
  • Pipeline refresh: Adopt LogC4-native LUTs; validate color across units in prep.
  • Data planning: ARRIRAW is heavy even with HDE—budget DIT time, storage, and turnaround.
  • Rigging reality: It’s still a high-end camera—pair with proper support, operators, and time.
