The ARRI cmotion cPRO system is a professional wireless lens control solution designed for first ACs who demand accuracy, reliability, and smooth ergonomics on fast-moving sets. Built around refined brushless lens motors and robust 2.4GHz long-range RF, cPRO delivers consistent pulls for focus, iris, and zoom with low latency and repeatable response. It integrates seamlessly with ARRI digital cinema cameras and plays well with third-party platforms, creating a flexible ecosystem for narrative, commercial, and documentary projects.

At the heart of cPRO is refined motor control precision. The system’s torque delivery and micro-step resolution translate into silky focus ramps and hard, repeatable stops without cogging. For lenses with long throws or tight mechanical tolerances, the motors maintain authority while staying quiet for sound-critical sets. Customizable speed curves, end-stop calibration, and lens mapping allow ACs to tailor behavior to vintage primes, modern cine zooms, and anamorphic glass, ensuring consistent marks and predictable feel across lenses.

Wireless resilience is central. The cPRO receiver uses spread-spectrum communication and adaptive channel selection to keep links stable in congested RF environments. The result is reliable control around video village, gimbals, steadicams, or car rigs where interference can derail takes. For complex builds, the system supports clean multi-channel operation, enabling simultaneous control of focus, iris, and zoom or splitting roles between operators for demanding sequences.

Lens data and metadata streamline post and continuity. With lens mapping profiles and range scaling, ACs can set witness marks quickly, swap glass with minimal downtime, and maintain consistent feel across focal ranges. When paired with compatible cameras and accessories, lens metadata can be passed for on-monitor overlays and recorded for VFX pipelines, aligning on-set decisions with downstream workflows and saving time in conform and finishing.

On-rig flexibility makes cPRO a natural fit for modern camera movement. The compact motors and receiver units mount easily on 15mm/19mm rods, gimbals, cranes, or handheld rigs. Low-profile brackets and reversible gears accommodate tight builds and short flange distances common with mirrorless-to-cine conversions. Power distribution is straightforward with standard camera power outputs, P-Tap feeds, and daisy-chain options to keep cabling tidy and balance intact.

Operator comfort drives the hand unit design. The cPRO controller features a high-precision focus knob with adjustable drag, assignable buttons for quick function calls, and a clear display for distance readouts, battery status, and channel info. Marker rings accept grease pencils for rapid mark updates, and virtual marks can be stored to recall shifts between talent positions or blocking changes. For zoom and iris, the ecosystem supports single- or dual-operator workflows, making it easy to split responsibilities on complex scenes.

Integration with camera systems is broad. With ARRI bodies, the cPRO architecture taps into established protocols for run/stop, status feedback, and accessory coordination, while third-party cameras connect via standard interfaces to maintain core functionality. The system plays well with wireless video and on-monitor overlays so the team can see distance and lens data where it matters, whether that is on a 7-inch director monitor or a compact on-handle screen for the focus puller.

On fast-paced sets, setup speed is critical. Auto-calibration finds lens end-stops quickly, profile recall loads saved lens data, and channel selection locks a clean frequency to start pulling within minutes. The system’s battery strategy is optimized for long days, and hot-swap options minimize downtime when coverage shifts or talent resets demand quick reactions.

As a camera rental partner, Unicorn Films supplies the ARRI cmotion cPRO as a production-ready lens control package. Each kit is assembled with pre-mapped lens profiles where available, calibrated motors, rod clamps, gear sets, motor cables, receiver units, power options, and spare mounting hardware. Our knowledgeable crew aligns the system with the selected camera, configures run/stop cabling, and provides best-practice guides for gimbal, handheld, vehicle, and crane setups. We aim to deliver hassle-free rentals that let first ACs focus on performance and precision rather than troubleshooting.

For teams that prioritize accurate marks, robust RF links, and versatile multi-channel control, ARRI cmotion cPRO stands out. It brings together motor finesse, intelligent mapping, dependable wireless, and ergonomic control to support confident pulls on the most demanding productions, from intimate close-ups to high-speed action.
