Modular housing system that wraps around the camera body, providing mounting points for monitors, mics, and other accessories.
Technical Details
Standard cages use 15mm Lightweight Support (LWS) rods with 60mm spacing or 19mm studio rods with 104mm spacing according to ARRI standard. Typical cage dimensions for a Sony FX6 are 195×140×85mm with a weight of 420g (aluminum) or 280g (carbon). The frames offer up to 32 threaded mounting points (1/4"-20 and 3/8"-16) as well as ARRI-compatible rosettes for handles. Cold shoes and NATO rails enable quick accessory mounting without tools.
Variants include half-cages (top only), full-cages (complete enclosure), and modular systems with detachable side panels. Special versions for cameras like RED Komodo or Blackmagic Pocket offer camera-specific cutouts for ventilation and controls.
History & Development
Redrock Micro introduced the first DSLR rigging system in 2008 with the microFollowFocus, after Canon 5D Mark II popularized video recording. In 2010, Wooden Camera established professional cage systems with the D90 Cage. SmallRig revolutionized the market in 2013 with cost-effective, camera-specific cages under €200.
Development followed the mirrorless revolution: from simple top-handle solutions to fully integrated ecosystem approaches. Tilta and ARRI expanded their systems with quick-release mechanisms and tool-free mounting between 2018-2020.
Practical Use in Film
"The Avengers" (2012) used Canon 5D Mark III in Redrock cages for crash cam shots. Netflix productions like "Mindhunter" systematically relied on SmallRig cages with Sony cameras for handheld sequences. Documentary filmmakers prefer half-cage setups with top handles for 6-8 hour shooting days.
The workflow begins with a camera-specific base cage, followed by rod system mounting and accessory build-up. Cages reduce setup time from 45 to 15 minutes compared to improvised mounting. Disadvantages: an additional 400-800g weight and limited camera ergonomics.
Comparison & Alternatives
Cages differ from top handles by offering 360° accessory access and from shoulder rigs by their compact design. Stabilizer integration requires quick-release plates, while traditional ENG cameras have integrated accessory interfaces.
Modern alternatives include in-camera stabilization and integrated XLR inputs, which reduce external rigging. Full-frame cameras like the Sony FX9 combine cage flexibility with ENG functionality. Gimbal systems like the DJI Ronin are increasingly replacing manual rigging solutions for moving shots.
Current News
Current cage systems are increasingly focusing on optimized cable management for lighter rigs and support for new codecs like H.265. Manufacturers like Tilta are expanding their cage ecosystems with specialized components such as the Hydra Arm Pro V2, which enables the integration of gimbals up to 8kg with its active damping system and quick-swap plates. This development shows the trend towards modular, weight-optimized cage solutions for modern production requirements.
