MRR-1 is a solid, ergonomically designed right-side camera handgrip with assignable user buttons and a control rocker for super-smooth zooming. It includes a steel ARRI rosette and two LBUS interfaces.
The Master Grips provide full control of focus, iris and zoom settings on cine lenses, including adjustable motor speed, zoom response and motor limits. They also offer a comfortable way to control the integrated servo motors of ENG and EF lenses*. Mounted on tripod pan bars or studio pedestal heads, the Master Grips can be used as focus and zoom demands for multi-camera setups, such as when using the AMIRA in Multicam mode. 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, updated with CUB-1 SUP 2.0.
Based on the classic ARRIFLEX handgrips trusted by generations of filmmakers, the Master Grips follow a proven ergonomic design. With controls that are easy to reach and yet protected from accidental triggering, they allow for prolonged handheld operating without any discomfort or strain. Constructed around a lightweight magnesium cast housing, the Master Grips are solid, rugged and reliable – able to withstand sustained use in harsh shooting environments.
Easy to use
With an intuitive user interface, the Master Grips are easy to set up either 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.
*EF and ENG lens support with ALEXA Mini/AMIRA SUP 5.0 – initially only iris support for EF lenses.

Three Axes – All Inclusive
The Wireless Compact Unit WCU-4 combines three axis of lens control with a lens data display in a compact and ergonomic housing. Weighing around 780 grams including battery, it’s one of the lightest hand units in its class, providing unrivaled comfort during a long working day.
ALEXA Remote Control
An optional software license will enable you to remote control all ALEXA Plus type cameras, except the ALEXA HD Plus. This includes setting frame rate, shutter angle, exposure index, false color on the monitor output, and more. Extended camera status information is also available, allowing you to quickly check your camera settings at any time.
Tactile vibrating feedback lets you keep your eye on the action in the most challenging situations. Operators can concentrate on the scene, knowing that the hand unit will vibrate to prompt them when focus markers are reached.
Backlit Focus Knob
The super-smooth focus knob contains an integrated light source that shines through the wide, optionally pre-marked focus ring in low light conditions, thus providing clearly readable focus marks at all times. The friction of the focus knob can be easily adjusted to one’s personal preference without any tools.
Easy-to-Read Lens Data Display
Clearly arranged, easy-to-read lens and camera information is available on the large 3” display, along with data from optional ultrasonic distance measurement devices. The transflective display technology ensures perfect readability in all ambient lighting conditions.
Pre-Marked Focus Rings
Lens scales can be mapped to a set of high quality pre-marked focus rings in metric or imperial scale.
The WCU-4 user button can be configured to activate focus tracking – setting the focus motor to continuously follow a subject by using an ultrasonic distance measurer. Focus tracking works with ARRI’s Ultrasonic Distance Measure UDM-1 and ALEXA Plus or Studio cameras or the Universal Motor Controller UMC-4.
Multiple Mounting Options
The Wireless Compact Unit WCU-4 features M4 mounting points on its top and bottom, and the optional WCU-4 Plate (K2.0006501) can attach to either, providing various 1/4-20 UNC and 3/8-16 UNC mounting points itself. When mounted on the bottom, the WCU-4 Plate serves as a table stand or can be used to accept a 3/8-16 UNC spigot for mounting on a C-stand. When mounted on top, it can be used to adapt the WCU-4 to an on-board monitoring system. Weighing only 67 g, the WCU-4 Plate is made of durable, aircraft-grade aluminum.
Various parameters of the WCU-4 can be set up to one’s personal preference. These include the display arrangement, vibration patterns and programmable user button, to name just a few. You can save your preferred settings on an SD card, enabling you to immediately personalize any WCU-4, anywhere in the world.
Exceptional Quality and Service
The WCU-4 is completely splash-proof and embodies the reliability and durability for which ARRI is famous. Wear and tear parts are replaceable at rental level, and the worldwide ARRI Service network ensures rapid second level support if needed. New firmware versions can be installed to the unit via SD card within seconds.
