SMALLRIG SR 3009

Professional Camera Cage Kit for Sony Alpha 7S III

The SmallRig SR 3009 Master Kit is designed specifically for the Sony Alpha 7S III full-frame mirrorless camera. It combines a form-fitting camera cage, an HDMI cable clamp, a NATO rail and a quick-release top handle to create a versatile foundation for video production. The kit improves handling during handheld recording and provides multiple mounting points for additional equipment, making it suitable for interviews, documentary work, commercial production and other demanding filming environments.

Protective Full Camera Cage

The included full cage is manufactured from aluminium alloy and shaped to fit the Sony Alpha 7S III. It surrounds the camera body with a rigid protective frame while providing a mounting structure for compatible accessories. Its fitted design helps maintain access to the camera’s controls, connectors and battery compartment, allowing the camera to remain practical to operate while equipped with additional rig components.

Quick-Release NATO Top Handle

The kit includes a top handle that attaches to the cage through the supplied NATO rail. The quick-release mechanism makes it possible to install or remove the handle efficiently when adapting the camera for different shooting situations. Its elevated gripping position provides improved control when carrying the camera or filming from low angles, while the handle’s mounting interface supports compatible accessories for expanding the rig.

Dedicated HDMI Cable Clamp

The HDMI cable clamp helps secure the cable at the camera connection and reduces the risk of accidental disconnection during recording. It attaches to the cage with a 1/4"-20 screw and two anti-twist locating pins. An adjustable sliding block accommodates compatible HDMI cables of different diameters, helping relieve strain on the camera’s HDMI port when an external monitor or recorder is connected.

Versatile Accessory Mounting System

The cage features multiple 1/4"-20 and 3/8"-16 threaded holes, ARRI-style locating mounts and a cold shoe mount. These interfaces allow compatible accessories such as monitor supports, articulated arms, microphones and compact lights to be installed in different positions. The NATO rail also provides a dedicated mounting interface for compatible quick-release handles and other NATO-compatible components.

Stable Mounting and Practical Operation

The cage is secured to the camera using a 1/4"-20 mounting screw, while its fitted structure helps keep the camera stable during use. The combination of the cage, top handle and cable clamp creates a more organized rig, with the cable clamp helping protect the HDMI connection and the handle providing a convenient carrying point. This arrangement is particularly useful when the camera is operated with an external monitor or other connected video equipment.
