SMALLRIG S1R II Cage Kit for LUMIX S1R II 4903

This robust camera cage from SMALLRIG improves handling and protection for Panasonic full-frame mirrorless bodies while keeping all ports and battery access available, making it practical for run-and-gun shoots and gimbal use. It combines secure mounting points with a built-in Arca quick release plate, so swapping between tripod, gimbal and handheld rigs is faster and smoother.

Key Points

The cage offers all-round protection with rubber pads to prevent scratches and preserves full access to ports, controls and the battery door. Three locking points secure the camera, using a base 1/4"-20 screw and two side locking adapters that reduce rotational play and keep the body stable during movement. A magnetic wrench is included to speed up assembly and removal, which helps on busy sets.

This kit adds multiple accessory mounting options for audio, monitoring and support. There are two cold shoe mounts for microphones or lights, a top NATO rail for the top handle and a left NATO rail for a side handle. Quick detach points and strap lugs on both sides and the base accommodate hand straps or shoulder straps for more ergonomic carry. Consider that the side locking adapters must be removed prior to initial installation, according to the manufacturer.

Usage Recommendations

Fit the cage by first removing the side locking adapters as advised, then secure the base screw and re-fit the lateral locks for the firmest attachment. Use the built-in Arca plate to attach to tripods or to DJI RS-series gimbals for quick transitions between stabilised and tripod setups. The dedicated 3/8"-16 top locating hole also suits ARRI-style monitor mounts if you need a more rigid display solution.

For audio-heavy shoots the two cold shoes mean you can mount a shotgun mic and a small LED simultaneously. The cable clamp for HDMI and USB-C helps prevent accidental disconnections when recording externally or when monitoring. Note that while the cage is compatible with Panasonic DMW-XLR1 and XLR2 units, certain top-handle combinations may require the removal of an XLR cable clamp for proper fitment as stated by SMALLRIG.

Positive Aspects

The kit balances protection and modularity, allowing a compact rig to grow with your needs, whether you add a side handle, an external monitor or shoulder support. It keeps the camera accessible and ready for quick battery swaps and card changes. The Arca quick release and the mix of 1/4"-20 and 3/8"-16 mounting options offer compatibility with a wide range of accessories and stabilisers.

SMALLRIG S1R II Cage Kit presents a straightforward way to make a Panasonic mirrorless body more versatile on set while keeping setup times low and accessory options plentiful.
