SmallRig’s Camera Cage designed for Sony A7RIII, A7M3, and A7III cameras is a precision-engineered accessory crafted to protect these mirrorless cameras while expanding their rigging capabilities. Made from durable yet lightweight aluminum alloy, this cage enhances stability, safeguards the camera body from damage, and offers multiple mounting points for essential filmmaking accessories, addressing the needs of professional videographers and content creators.
Precise Fit and Solid Protection
Form-Fitting Design
The cage is shaped precisely according to the dimensions of the Sony A7RIII, A7M3, and A7III, ensuring a snug, vibration-free fit. It mounts securely using a 1/4″-20 screw underneath and a secondary M2.5 screw on the side to mitigate any twisting or wobbling during use. Rubber padding on the base adds further protection against scratches and enhances grip stability.
Durable Aluminum Construction
Constructed from high-quality aluminum alloy, the cage offers excellent toughness while remaining lightweight enough not to burden the operator during handheld shooting. Its rigid build delivers reliable protection against bumps and knocks, thus extending the camera's lifespan in demanding shooting environments.
Extensive Mounting Options for Accessories
Multiple Threaded Mounts
The SmallRig cage offers extensive 1/4″-20 and 3/8″-16 threaded holes all around the body, providing numerous attachment points for a range of accessories including microphones, monitors, LED lights, and magical arms. These universal mounts facilitate customization tailored to unique shooting setups.
ARRI-Style Anti-Twist Mounts
Additionally, the cage includes ARRI-style locating holes that prevent accessories from twisting or shifting after installation, ensuring stable and reliable mounting of heavy or critical gear like external monitors or EVFs.
Cold Shoe Mount
A built-in cold shoe on the top provides an immediate mounting point for a flash, microphone, or other compatible accessories.
HDMI Cable Protection
The cage integrates an HDMI lock system designed to secure the HDMI cable firmly in place, preventing accidental disconnection or cable damage that could interrupt video recording or live streaming.
Ergonomic Enhancements
For improved handheld shooting comfort, kits often come with a rubber NATO handle attached to a NATO rail mounted on the top of the cage. This not only improves grip but also offers more flexibility in handling the camera during movement-heavy shoots.
Full Camera Access
A thoughtfully open design maintains easy access to all essential camera functions including ports, buttons, battery compartment, memory card slots, and the hot shoe, so users never need to remove the cage for regular operation or quick battery changes.
