The AM-4 Magic Versa Arm from Leofoto is a multi-purpose tripod accessory mount that attaches to the leg spider of select Leofoto tripods, or other tripods and camera brackets with a 1/4"-20 receiver. The 9.8" Magic Versa Arm allows a light, microphone, monitor, smartphone, tablet, or even an additional camera to be affixed to a camera rig without the added bulk of a clamp. Each end of the AM-4 features a ball-and-socket joint that rotates 360°, and the center elbow joint locks in any position. The large, easy-to-grip center knob locks all three movements simultaneously for quick and easy setup and repositioning.
