ARRI MRR-1 Master Grip Right Rocker

The ARRI MRR-1 Master Grip Right Rocker combines effective camera stabilization with comprehensive lens and camera control. Lightweight and built to ARRI’s stringent quality standards, the Master Grip is designed for ALEXA, AMIRA, and third-party camera users who need flexible and responsive fingertip control while shooting handheld. MRR-1 is a solid, ergonomically designed right-side camera handgrip with assignable user buttons and a rocker switch for exceptionally smooth zoom control. It includes a steel ARRI rosette and two LBUS interfaces.

Versatile Controls

The Master Grip provides full control of focus, iris and zoom settings on cine lenses, including adjustable motor speed, zoom response and motor limits. It also offers a comfortable way to control the integrated servo motors of ENG and EF lenses*. The Master Grip can be used as focus and zoom demand for multi-camera setups, such as when using the AMIRA in Multicam mode (when mounted on tripod pan bars or studio pedestal heads). Camera control functionality includes user button access and REC start/stop for ARRI and third-party cameras, with the latter requiring the LCUBE CUB-1 accessory (sold separately), updated with CUB-1 SUP 2.0.

Proven Design

Based on the classic ARRIFLEX handgrips trusted by generations of filmmakers, the Master Grip features a proven ergonomic design. With controls that are easy to reach yet protected from accidental triggering, it allows for prolonged handheld operating without discomfort or strain. Constructed around a lightweight magnesium cast housing, the Master Grip is solid, rugged and reliable, able to withstand sustained use in harsh shooting environments. 

Easy to Use

With an intuitive user interface, the Master Grip is easy to set up, via the integrated touchscreen or physical buttons. The controls are fully configurable and a status readout boosts user confidence, with the multilingual display allowing menus and status to be read in English, Chinese, Spanish or German.
