The SmallRig Cage (4183) for Sony FX3 / FX30 is a full protective and modular camera cage designed to expand rigging options for Sony’s FX-series cinema cameras. It is built from durable aluminum alloy and secures the camera firmly using multiple 1/4"-20 screws to prevent twisting while maintaining full access to buttons, ports, and the battery compartment. The cage features a removable top NATO rail (for attaching the original Sony XLR top handle), a built-in HDMI cable clamp for protecting the port connection, and multiple mounting points including 1/4"-20 threads, ARRI locating holes, a cold shoe mount, and side NATO rails for accessories like monitors, microphones, side handles, and follow-focus systems. It also includes an Arca-Swiss base for quick tripod or gimbal mounting, making it a highly versatile and widely used rigging solution for professional video production setups.
