Ikan STR-A7IV STRATUS Complete Cage

Complete Cage Kit for Sony Alpha a7 Series Cameras

The Ikan STR-A7IV STRATUS Complete Cage is a full-featured cage system designed specifically for Sony a7R IV, a7R III, a7 III, and a7S II mirrorless cameras. Engineered for professional filmmakers and photographers, this robust aluminum cage offers secure mounting, full port access, enhanced cable management, and a wide range of threaded mounting options. Whether you’re working handheld or building a complete rig, this system supports your workflow without compromise.

Formfitting Design with Full Control Access

This cage securely wraps around your Sony a7 series body while maintaining clear access to buttons, dials, battery door, and media card slots. Its formfitting structure is tailored to prevent unwanted movement without obstructing usability. The integrated Arca-Swiss base plate allows for quick-release mounting to compatible tripod heads or the included rod base for rig expansion.

Integrated Rod Baseplate for Rig Builds and Lens Support

The base of the system includes dual 15mm LWS rod clamps with locking levers and two 15mm rods, ideal for supporting accessories like matte boxes, follow focus systems, or lens motors. A built-in 1" vertical adjustment range lets you align the camera precisely with rod-mounted gear, ensuring compatibility across a wide range of lenses and accessory positions.

Top Handle with Mounting Threads and Rod Clamp

A removable top handle is included, mounting securely with screws and providing a comfortable grip for low-angle shots and easy transport. The handle includes a cold shoe, multiple 1/4"-20 and 3/8"-16 threads, and a single 15mm rod clamp—ideal for mounting lights, monitors, EVFs, or audio gear directly on top of your cage.

Dedicated Cable Clamp for Secure Connections

An adjustable HDMI/USB cable clamp is mounted on the cage to protect critical connections from accidental tugs or loosening during operation. This feature is especially useful when working with external recorders, monitors, or SSDs that require continuous signal integrity throughout a production.

Versatile Mounting Options for Accessories and Tripods

Across the cage’s body are multiple accessory mounting points, including 1/4"-20 and 3/8"-16 threads with ARRI locating pin holes to prevent accessory twist. The base of the cage features tripod-compatible threading for secure mounting to a wide variety of plates and heads, ensuring your rig stays locked in place whether handheld, tripod-mounted, or gimbal-balanced.
