Cages
Without question, the Sony a7S III is a mirrorless camera meant for video. Impressive specs and image quality are wonderful, but it has the same problems for video as every other mirrorless camera: its form factor is better suited to stills. One solution is to get a cage, such as this Master Kit from SmallRig that I was able to take for a spin.
Attention all Sony mirrorless aficionados: If you’re upgrading to the new Sony Alpha a7S III, SmallRig has the cage for you. Grab the new SmallRig Camera Cage for Sony a7S III to both cradle your camera in four-sided protection and add multiple accessory mounting options.
Powering your Sony PXW-FX9 camera with a professional V-mount battery and adding numerous accessories has never been easier, when you use the durable aluminum Camera Cage with Battery Plate, from Tilta. The modular cage consists of multiple parts, starting with the V-mount battery plate that installs on the back of the camera.
