Overview
Key Features
Compact FX6 Cage - SmallRig FX6 Rig Kit is a lightweight and compact cage designed for videographers who prefer shooting on various scenarios such as tripods, handhelds, and shoulder rigs, etc. This complete FX6 cage kit solution provides both protection and attachment points for accessories.
With a Slidable V-Mount Battery Plate - Equipped with a V-mount battery plate and a cable that quickly switches among different scenarios without repeatedly disassembling and installing batteries. The V-mount battery plate supports slide up and down without blocking the memory card and BP-U battery installation.
Both V Mount and BP-U Battery Are Compatible - When using both, please note that the BP-U battery needs to be installed before the V-mount battery when installing, and the V-mount battery needs to be removed before the BP-U battery when uninstalling.
Dual Position Mounting Side Plate - The side plate is compatible with the original control grip when mounted on the rear, making it easy to expand your accessories, such as microphones and image transmitters. When mounted on the front, it can easily balance the center of gravity when shooting vertically.
Multiple Mounting Points - The FX6 cage includes built-in 1/4''-20 locating holes (same as those in the camera), 1/4"-20 threaded holes, 3/8"-16 threaded holes, 3/8"-16 locating holes for ARRI, and a cold shoe mount for the microphone, image transmitter, monitor, etc.
