SmallRig 4183B Camera Cage for Sony FX30 and FX3

Protect and mount a variety of accessories onto your Sony FX3 or FX30 camera with this lightweight 4183B Camera Cage from SmallRig. This formfitting aluminum cage maintains access to the camera's controls and features a variety of mounting options. The 4183B version of the cage features an HDMI cable clamp constructed of PC and fiber for a lighter form factor. The camera mounts onto the cage using 1/4"-20 screws on the bottom and the side to prevent twisting, and rubber padding on the base protects the camera.

In addition to a shoe mount, a removable NATO rail, and multiple 1/4"-20 and 3/8"-16 accessory threads, the cage features ARRI-style accessory mounts for preventing accessories from twisting when mounted on the cage. The cage also features an integrated Arca-style base that allows you to use standard Arca-style tripod heads and gimbal mounts. There are strap slots on either side of the cage to add a camera strap. A built-in screwdriver on the bottom allows you to secure the camera screws.

The included NATO rail must be removed for use with the original Sony XLR handle.

SmallRig Advanced V-Mount Battery Mounting System

Add a V-mount battery or a power solution of your choice to your camera rig with SmallRig's Advanced V-Mount Battery Mounting System, which includes a V-mount battery plate, an Arca-type quick release plate to easily mount your camera, two 15mm rods that attach to the chest pad for handheld shots, a V-lock accessory wedge, and a replacement V-mount backplate.

The modular design of the baseplate features two 1/4"-20 and one 3/8"-16 thread to mount a quick release plate of your choice. The included Arca-type quick release plate is compatible with DJI RS-series gimbals, and multiple 1/4 "-20 threads on the battery plate allow you to mount accessories or power solutions apart from a V-mount battery, such as an NP-F battery plate or a battery bank holder. In tandem with the V-lock accessory wedge, you can attach any power solution to your camera rig quickly via V-mount.

The versatility continues with a dampened battery plate that can rotate 90°, allowing for an unobstructed view of your camera's viewfinder and enough room for articulating screens. The adjustable baseplate can extend 1.44" to fit cameras up to 4.37" in depth, and the shortened 4.13" 15mm rods, in combination with a larger chest pad, increase stability and reduce fatigue for prolonged handheld shots. The chest pad mount integrates an Allen key on the bottom and features a quick release button to adjust the configuration easily.

Can the top rail be removed from the cage in order to make room for the Sony XLR-H1 top handle?
Asked by: Tanner
Yes, the SmallRig 4183B Camera Cage Kit with V-Lock Battery Plate for Sony FX30 and FX3 comes with a separate NATO rail that you would not attach while using the Sony XLR-H1 XLR Handle Unit.
