I have the Zhiyun Crane M2. It is a bit more tricky to balance than the purely phone gimbals. The only time I use it is when I need to walk from my office to the lab for a demo. Even then it has only been practice and never live to my students.
You can run them without their official software, so you can use something like EpocCam that connects your phone as a webcam. EpocCam works wired or wireless, so you can go walkabout anywhere on the same network. Lag is pretty good on wireless and non-existent on wired.
I’ve been looking at a couple of new phone Gimbals that are more like selfie sticks, and less expensive. They don’t have all the axes, but can work like a cam on a tripod. Zhiyun make one for $50, and I’ve seen a few other brands.
The gimbal doesn’t connect to ManyCam, so it is really just a fancy tripod. Would be cool if you could control it remotely from ManyCam.
