SmallRig Support Cage for Sony a9 III Overview

The formfitting Camera Cage from SmallRig protects and offers accessory mounting for your Sony a9 III camera. The durable aluminum cage maintains open access to the camera's controls and features a variety of mounting options. It features multiple 1/4"-20 threads and ARRI-style 3/8"-16 anti-twist mounts for attaching accessories.

There are multiple 1/4"-20 and 3/8"-16 tripod mounting threads on the bottom to add an optional quick release plate or mount onto a tripod. The camera mounts onto the cage using a 1/4"-20 screw, and there's a side lock and rubber padding on the base also helps prevent twisting and scratching. An integrated strap slot allows you to add an optional wrist or shoulder strap, and there is also a QD (Quick Detach) port. A screwdriver is included to secure the screws, and it stores in the base of the cage.

SmallRig Support Cage for Sony a9 III Reviews

Does what I need it to do... however...

By David
Rated 4 out of 5

Has all the mounting points that I need, and doesn't get in the way of any controls. Also doesn't restrict the use of the rear screen. However, it adds quite a bit of thickness around the grip, which may quickly lead to a hand fatigue unless you have very large hands. I think a clutch style strap might be required if you expect to be hand holding for any long shooting sessions with this cage attached.

Battery access is fine

Reviewer who posted battery door issue didn't realize that there is a flip out arm that allows the battery door to fully open. Thanks for returning the cage so I can get used pricing for it. Design is adequate. I'd like to see more attach points. The HDMI clamp is a little kludgy.

Asked by: Coastal
The SmallRig Camera Cage for Sony a9 III is exclusively for the Sony A9 III body. Even though the body of the a1 II shares a similar body, Smallrig will be releasing a new cage model for the Sony a1 II shortly.

Will this obstruct PL mount adapters with VND?

Will this obstruct PL mount adapters with VND?
Asked by: Sonny
It will depend on the PL lens mount adapter, but there is a potential for the NATO rail on the port side of the cage on the SmallRig Camera Cage for Sony a9 III to obstruct certain Variable ND gears on PL lens mount adapters.
