SMALLRIG SR 3007

Full Camera Cage for Sony Alpha 7S III

The SmallRig SR 3007 is a full camera cage designed specifically for the Sony Alpha 7S III full-frame mirrorless camera. It surrounds the camera body with a fitted aluminium frame, providing additional protection and multiple mounting points for accessories used in photography and video production. The cage is suitable for handheld filming, tripod-based setups and more advanced video rigs, while preserving access to the camera’s main controls and functions.

Lightweight Aluminium Construction

The cage is made from aluminium alloy, combining a rigid structure with a relatively low weight. Its dimensions are approximately 145.5 × 106.5 × 64 mm, and its net weight is around 255 g. The fitted design follows the contours of the Sony Alpha 7S III, helping maintain a compact camera setup while providing a stable framework for mounting additional equipment.

Secure Camera Mounting and Protection

The camera is attached using an integrated 1/4"-20 mounting screw, while the cage’s anti-twist design and protective padding help keep the camera securely positioned. This arrangement reduces unwanted movement between the camera and cage during normal operation and helps protect the camera body from direct contact with the metal frame. The structure also provides additional support when accessories are attached to the cage.

Dedicated HDMI Cable Clamp

The included HDMI cable clamp helps prevent accidental cable disconnection during recording and reduces strain on the camera’s HDMI port. It attaches to the side of the cage using a 1/4"-20 screw and two anti-twist pins. A knurled adjustment screw moves a sliding block that can be tightened around HDMI cables of different diameters, helping maintain a stable connection when using an external monitor or recorder.

Versatile Accessory Mounting Points

Multiple 1/4"-20 and 3/8"-16 threaded holes provide mounting options for compatible accessories, including monitor mounts, articulated arms and additional handles. ARRI-style locating mounts help prevent compatible accessories from twisting under load. These attachment points allow the cage to be configured for different shooting requirements without relying on a single mounting position.

Integrated NATO Rail and Cold Shoe

A NATO rail is built into the left side of the cage for attaching compatible NATO-clamp accessories, such as suitable side handles. A cold shoe mount provides an additional attachment point for equipment such as a compact microphone, wireless receiver or small LED light. Strap attachment points are also included for compatible wrist or neck straps, offering further options for carrying and handling the camera.

Compatibility and Package Contents

The SmallRig SR 3007 is designed for the Sony Alpha 7S III. The cage preserves access to the camera’s controls, connectors, hot shoe and battery compartment. A screwdriver is integrated into the bottom of the cage to simplify tightening the camera mounting screw. The package includes one camera cage, one HDMI cable clamp and one Allen wrench. Handles, monitors, cables and other accessories are sold separately.
