The ARRI LCUBE CUB-2 is an incredibly compact and versatile converter designed to bridge the gap between traditional ENG-style servo zoom lenses and ARRI's sophisticated Electronic Control System (ECS), particularly when using ARRI Master Grips or Stabilised Remote Heads (SRH).

At its core, the CUB-2 adapts servo-zoom lenses (typically connected via a 12-pin Hirose-type cable) to the LBUS system (Lemo 4-pin). This intelligent conversion allows ARRI Master Grips or other LBUS-compatible controllers to directly take over focus, iris, and zoom control of the ENG lens, transforming a broadcast-style zoom into a cinema lens control solution.

A key feature is the integrated switch that allows operators to easily select between iris control from the camera (utilising the lens's auto-iris functionality via the camera's Hirose interface) or directly from the Master Grips/LBUS system.

The CUB-2 is remarkably lightweight and compact, making it easy to integrate into any camera rig. It features an integrated dovetail, allowing it to be securely mounted using the included LCUBE Bracket or other compatible clamps. For cinematographers seeking to leverage the speed and versatility of ENG-style zooms with the precision and control of ARRI's ECS, the LCUBE CUB-2 is an indispensable tool, streamlining complex setups and enhancing operational efficiency on set.
