Ikan STR-A7III STRATUS Complete Cage for Sony a7 III Series Cameras

Formfitting Cage System for Sony a7 III Series Cameras

The Ikan STR-A7III STRATUS Complete Cage is an all-in-one rigging solution built to enhance the functionality of your Sony a7 III, a7R III, or a7S II mirrorless camera. Designed for filmmakers and content creators looking for mounting flexibility and dependable camera support, this aluminum cage surrounds your camera with threaded mounting points, secure accessory clamps, and compatibility with Arca-Swiss, NATO, and 15mm rod systems—all while keeping your camera’s buttons, ports, and battery accessible.

Designed for Full Access and Rig Expansion

This cage is form-fitted to maintain full usability of the camera, with cutouts around the battery compartment, SD card slot, HDMI port, and other I/O interfaces. It mounts the camera securely using a 1/4"-20 screw and adds additional support without compromising ergonomics. With ARRI locating pins, 1/4"-20 and 3/8"-16 threaded holes, and a shoe mount, it provides a sturdy base for attaching everything from monitors to wireless systems.

NATO Top Handle Offers Mounting Flexibility

At the top of the cage is a NATO rail for attaching the included top handle, which features its own cold shoe and threaded mounting holes. The top handle supports a bicycle grip for better comfort and control, especially during handheld or low-angle shots. This makes it easier to reposition the camera on set or carry the entire rig from one location to another.

Integrated Arca-Swiss Plate and Rod Clamp Base

The base of the cage features an integrated Arca-Swiss plate, offering quick transitions between handheld, gimbal, and tripod setups. Below that, an adjustable rod clamp supports both 4" and 8" 15mm rods, allowing you to align matte boxes, lens motors, or follow focus systems with precision. The included rod system is modular, enabling extension for longer lens setups.

Cable Clamp Protects HDMI and USB Connections

A removable cable clamp is included with the cage to secure your HDMI and USB cables, preventing accidental disconnection or wear on the ports. The clamp adjusts to fit various cable sizes and locks in place to protect fragile connectors during movement or extended use. This feature is especially important when recording to external monitors or SSDs.

Versatile Mounting Points for Accessories

Whether you're building a lightweight mobile setup or a fully loaded shoulder rig, the STRATUS cage provides multiple options to mount arms, audio gear, or lighting. The extensive layout of mounting threads ensures balanced rigging, while ARRI rosettes and locating pins deliver extra support for heavier builds. Its low-profile and lightweight aluminum construction makes it a perfect base for professional video capture.
