FilmCube FX CINE EXTENSION is a unified rig core for the Sony FX3/FX30 that delivers the Sony cinema look while integrating power, mounting, and clean cable routing into one cohesive rear system.

Unified rig core: Power, mounting, and routing are engineered as one rear architecture so your FX3/FX30 build stays cohesive and intentional.
Tool-free assembly: Two-point thumb screw mounting lets you build up and tear down fast without reaching for extra tools.
Cable-free battery swaps: A clean V-mount setup keeps cables off the battery so swaps are quick, simple, and hassle-free.
Integrated power control: A master power switch and voltage meter give you instant control and at-a-glance confidence on set.
Multi-output accessory power: Four D-Tap outputs and regulated USB-C ports make it easy to run monitor + wireless/timecode from one battery.
Controlled internal routing: Inward cable paths keep runs protected and tidy—reducing snag points and keeping the rig visually clean.
