Godox Metal Smartphone Clip MTH03. Unlike other mounts that are spring-loaded or require you to undo a screw, the MTH03 opens and locks closed with a simple lever on the back. The clamp can secure any phone from 2.4 to 3.3″ in width and padded to protect its surface. For added shooting versatility, you can use the bottom or side 1/4″ screw hole to mount the clamp to a tripod in either landscape or portrait orientation. A top cold shoe is also integrated for an optional accessory, such as an LED illuminator or external microphone.
