SMALLRIG SR 3668

Camera Cage Kit for Sony Alpha Cameras

The SmallRig SR 3668 Basic Kit is a camera support system designed for the Sony Alpha 7R V, Alpha 7 IV and Alpha 7S III. It combines a protective camera cage, an ergonomic top handle and an HDMI cable clamp to provide a practical foundation for handheld video production, photography and more advanced camera setups. The kit adds protection and mounting flexibility while preserving access to the camera’s essential controls and functions.

Protective Cage Construction

The camera cage surrounds the camera body, helping protect it from everyday impacts and accidental contact during filming, transportation and equipment changes. Its fitted design provides a secure mounting platform without unnecessarily obstructing normal camera operation. The cage is intended to support a range of shooting configurations, from a compact handheld setup to a more elaborate rig equipped with additional accessories.

Ergonomic Top Handle

The included top handle provides an additional point of contact for carrying the camera and controlling its movement. Its position above the camera makes it useful for low-angle filming, ground-level compositions and shots that require the operator to move the camera close to the subject. The handle can also make repositioning the camera more convenient when working between handheld and stationary shooting arrangements.

Dedicated HDMI Cable Clamp

The kit includes an HDMI cable clamp designed to secure the cable at the camera connection. By reducing unwanted movement and strain around the connector, the clamp helps protect the camera’s HDMI interface and supports a more stable connection when using an external monitor or recording equipment. The clamp attaches to the cage with a screw and locating pins, helping keep it properly positioned during operation.

Mounting Points for Accessories

The cage incorporates multiple mounting options for building a camera rig around the needs of a particular production. These include 1/4"-20 threaded holes, ARRI-style 3/8"-16 locating holes, cold shoe mounts, NATO rails and a QD socket. They can be used with compatible monitor mounts, microphones, LED lights, handles and other accessories, allowing the setup to be adapted for different filming requirements.

Secure Installation and Practical Details

The cage is designed to provide a stable connection between the camera and the attached rig. Its construction includes provisions for attaching accessories and hand straps, while the integrated magnetic flat-head screwdriver and hex spanner help simplify assembly and adjustment. These practical details are useful when preparing equipment on location or changing the configuration between different shooting tasks.
