The MeFOTO SideKick360 Smartphone Tripod Adapter in purple is a support for 2.3 to 2.8" wide smartphones that provides stability and allows for enhanced creative control over photos and videos shot with the phone's built-in camera. The aluminum Arca-Swiss style quick-release base works with full-size tripods and any Arca-Swiss style quick-release clamp. The adapter is equipped with three 1/4"-20 threads and one 3/8"-16 thread, allowing it to be mounted to a variety of quick-release plates, monopods, and handles. The flexible ball joint allows for 360-degree rotation, so you can situate your phone in either portrait or landscape mode, and the flat base allows it to be used by itself as a stand.
