The Feiyu Vimble 2A provides motorized pan, tilt, and roll motion control for the GoPro HERO8, and it's also capable of telescoping out an additional 7.2". The extra length lets you capture selfie videos as well as shoot from various creative angles.
The Vimble 2A comes with a mounting clip that supports the HERO8. The gimbal also allows direct control of these cameras from the gimbal buttons by syncing the two to the companion Feiyu ON iOS/Android app. Additionally, optional Feiyu adapters can be used to attach the Osmo Action, YI, SJCAM, and Feiyu Ricca action cameras. All of these will also be supported for camera control except the Osmo Action, which you will only be able to stabilize. Camera control includes functions such as record start/stop and time-lapse capture.
