ARRI K2.72114.0 overview

  • 1Description

Use ARRI's CLM-4 Motor to remotely control your lens's focus, iris, or zoom function. The high-end, solidly-built CLM-4 motor features smooth, quiet control for standard lenses. This basic motor component of ARRI's modular ECS (electronic control system) can be fleshed out with separately available gears, cables, and brackets compatible with the ARRI or third-party camera of your choice. The CLM-4 motor can be used with ARRI's UMC-4 Universal Motor Controller and SMC-1 Single Motor Controller.

For optimal flexibility, a gear can be attached to either side of the CLM-4 Motor, expanding position choice to either side of the lens, and either over or under the lens barrel depending on your camera configuration.
