Product Information
Full details
The SmallRig 4183 Cage is a precision-engineered solution for Sony FX3 and FX30 users who need a robust, lightweight foundation for professional video rigs. Designed to offer maximum accessory mounting potential while maintaining full access to camera controls, it is the ideal choice for run-and-gun filmmakers and studio operators alike. While the cage significantly increases mounting versatility, it does add a slight amount of bulk to the camera body, which may affect fit in ultra-compact camera bags.

Troubleshooting
Camera feels loose or wobbles inside the cage.
Check that both the bottom screw and the side locking screw are fully tightened using the provided magnetic tool.
XLR handle will not attach to the NATO rail.
Ensure the modular NATO rail is securely fastened to the cage and that the handle's safety pins are not obstructing the slide-on mechanism.
HDMI cable clamp is not holding the cable.
Adjust the clamp position along the rail to ensure it is pressing firmly against the connector housing, not just the cable jacket.

Setup, Compatibility & Care
To install the cage, align the camera body within the frame and use the included magnetic spanner to secure the bottom 1/4"-20 screw and the side lock screw. Ensure the rubber padding is clean before seating the camera to maintain grip. The cage is specifically compatible with the Sony FX3 and FX30 models. To maintain the cage, occasionally inspect the screws for tightness after heavy use. Keep the rubber contact pads free of debris using a soft brush. For the HDMI clamp, ensure the cable is looped properly to avoid putting direct tension on the port itself.
