Rent NowThe SmallRig Extension Cage Kit for Canon EOS R6 Mark III/R6 II/R5 II (Basic) 5955 is a dedicated and essential accessory package for videographers and filmmakers using the Canon R-series mirrorless cameras. This “Basic” kit is designed to protect the camera body while vastly expanding its accessory mounting capabilities and improving handheld stability.
Kit Components (Model 5955)
The Basic Extension Cage Kit includes three main items:
Full Camera Cage: A formfitting aluminum alloy frame that wraps around the camera body, protecting it from accidental damage without obstructing access to ports, controls, or the battery door. It features a three-point locking system (one screw on the bottom, two locating blocks on the sides) for secure, anti-twist mounting.
Top Handle: An ergonomic handle, often with silicone padding, that attaches to the top of the cage. This provides a comfortable grip for low-angle shots and improves camera stability for handheld work.
HDMI & USB-C Cable Clamp: A thumbscrew-tightened clamp that secures video and data cables, preventing accidental disconnections or port damage during filming.
Key Features and Expansion
Versatile Mounting: The cage is covered in numerous industry-standard mounting points, including 1/4″-20 threaded holes, ARRI 3/8″-16 locating holes, cold shoe mounts, QD (Quick Detach) interfaces, and strap slots.
Quick Release Ecosystem: The base of the cage features an integrated Arca-Swiss quick release plate, allowing for rapid transition between handheld shooting, tripods, and gimbals compatible with the DJI RS series (RS 2, RSC 2, RS 3 Pro, etc.).
Compatibility: The kit is tailor-made for the Canon EOS R6 Mark III, R6 Mark II, and R5 Mark II.
Important Compatibility Note: When using this kit with the Canon EOS R6 Mark II camera, the included cable clamp is incompatible. A separate SmallRig cable clamp (model 2981B) must be purchased for proper HDMI/USB cable protection with that specific camera model.
