A pair of Master Grips provide full control of focus, iris, and zoom settings on cine-style lenses, and offer comfortable control of integrated servo motors on ENG- and EF-type lenses. Focus, iris, and zoom speeds are adjustable, and end limits can be set for easier single-user moves. Camera controls include the REC function, and access to user buttons for both ARRI and third-party cameras. A separately-available LCUBE CUB-1 is required for third-party camera control.

The ergonomic design of the Master Grips reduces strain, enabling extended handheld operating; an "eyebrow"-type shield protects against accidental triggering and doubles as a finger rest. This right-handed rocker is one of four available Master Grip options that can be combined in right- or left-handed pairs. The rocker grips enable super-smooth zooming, while the thumb wheels are suited for focusing or iris, or adjustments. An integrated touchscreen and a 5-way joystick each offer easy setup of the ARRI Master Grips.
