In a simple, ABS plastic design, the Ulanzi G8-9 Plastic Cage allows you to expand your HERO8 with accessories such as lights, mics, and ND filters for vlogging, livestreaming, and most other applications. It comes with a 52mm threaded filter adapter and a shoe mount that can be attached on top. On the bottom, it provides space for a mic adapter and has a 2-prong mount for attaching directly to various supports. The cage leaves access to the USB port of the camera for connecting your audio adapter as well as for charging the camera during use. A lens cover is also included for protecting the lens when not using the camera.
