SmallRig 4903 Cage Kit for Panasonic LUMIX S1R II

Built for filmmakers and content creators who want a more secure handheld setup, the SmallRig 4903 Cage Kit adds protection, comfort, and mounting options to the Panasonic LUMIX S1R II. It includes a camera cage, an HDMI/USB-C cable clamp, and a top handle that attaches via a NATO clamp for fast setup and improved handling.

The ergonomic top handle helps deliver a steadier grip during shooting, while the thumbscrew cable clamp keeps both HDMI and USB-C connections locked in place at the same time. Multiple accessory mounting points make it easy to expand your rig with practical tools like a microphone, LED light, monitor, or SSD holder.

For even more flexibility, the cage features 1/4"-20 threaded holes, ARRI 3/8"-16 mounting points, a HawkLock H21 NATO rail on the left side, and strap slots on both sides for hand straps. An Arca-Swiss quick release plate is also integrated, making the kit compatible with Arca-Swiss tripods and DJI RS series gimbals.
