SmallRig 3669 Overview

Add accessory mounting and protection for your Sony a7 IV, a7R V, or a7S III mirrorless camera with this lightweight Advanced Kit from SmallRig. The kit includes a formfitting camera cage, two locking side plates, an HDMI cable clamp, a side handle, and a top handle with a 3/8"-16 ARRI-style accessory mount.

The formfitting aluminum cage features a 1/4"-20 camera screw, two locking side plates to prevent twisting, multiple 1/4"-20 and 3/8"-16 ARRI-style accessory threads, a NATO rail, a QD (Quick Detach) port, and strap slots. It maintains access to the camera's controls and hot shoe, and it features a variety of mounting options. The HDMI cable clamp protects your HDMI cable from pulling or disconnecting. The top handle provides additional shoe mounts and mounting threads, and the side handle provides additional mounting options and comfortable handheld support to the side of the cage.

SmallRig Full Camera Cage for Select Sony Alpha Series Cameras

Custom-fit to select Sony a7 and a1 models, this Full Camera Cage from SmallRig protects your camera while providing a myriad of mounting points for customizable gear configurations. The design of the cage maintains access to the camera's buttons and ports thanks to a hinged arm for battery replacement, among other custom details. Integrated locking side plates with M2.5 screws can be adjusted depending on the camera model you are using, for extra security.

Multiple 1/4"-20 threads and ARRI anti-twist 3/8"-16 threads throughout the cage offer mounting points for articulating arms. Two cold shoe mounts and a NATO rail can accommodate wireless transmitters, fill lights, or side handles. The bottom of the cage features an Arca-type quick release plate for easy integration onto a tripod or stabilizer. The cage's overall aluminum alloy and stainless steel construction creates a durable and lightweight design, and rubber pads on the interior protect the camera from scratches.

Can I easily mount (and unmount) this cage onto a tripod?

Yes, The SmallRig Professional Camera Cage Kit for Sony a7 IV & a7S III can be connected to your tripod's plate directly.

Say I am a7iii , with a NINJA V and Rode wireless go like in one of those images above , Is there an ADDITONAL spot on this rig to mount a Sony NPA-MQZ1K Multi Battery Adapter Kit for continuous shooting / longer battery life ? What side would the Sony NPA-MQZ1K Multi Battery Adapter Kit mount on if I have my atmos ninja v and a ride go I mic in the shoe mounts ? I don't see a place for the Sony NPA-MQZ1K Multi Battery Adapter Kit?? Please Clarify
Asked by: Mohamed
The Sony NPA-MQZ1K Multi Battery Adapter Kit has three 1/4"-20 mounting sockets on the top and the three on the bottom, you can use any number of 1/4"-20 connections to secure the battery adapter to any of the available 1/4"-20 mounting sockets on the SmallRig Professional Camera Cage Kit for Sony a7 IV & a7S III. Maybe consider mounting the adapter to the bottom for the most stream lined setup.
