Its function is an electric panoramic head that is mounted on a tripod (camera stand), and it makes the camera automatically rotate 360 degrees. It is often used for: * 📸 Shooting panoramic photos. * 🎥 Shooting smooth-moving time-lapses. * 🎬 Shooting professional rotating videos. * 📱 Cameras like Sony, Canon, Nikon, and some mobile phones can be mounted on it if you have a suitable holder. I haven't used it at all, it's new.
