SmallRig Universal Quick Release Cage for Mobile Phone 4299 provides a professional and convenient solution for mobile video shooting and live broadcasting. The cage features cold shoe mounts and 1/4"-20 threaded holes on the frame, allowing users to easily attach lights, microphones, tripods, side handles, top handles, and other equipment when shooting with mobile phones.Whether you're connecting a side handle, top handle, or tripod, this cage is not only compatible with standard products attached using a 1/4"-20 screw but also supports SmallRig's new quick release ecosystem, providing convenience, speed, stability, and efficiency. When using a mobile phone with MagSafe for stable static shooting, you can attach the phone directly to the MagSafe base on the cage. If you're using a phone without MagSafe or shooting dynamic scenes, you should use the included phone clip to secure the phone before shooting.
