TheĀ Leofoto AM Series "Heavy-Duty" Versa Magic ArmĀ is a multi-purpose tripod accessory that attaches to theĀ legĀ of select Leofoto tripods, or other tripods and camera brackets with a 1/4"-20 accessory slot. The magic 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 magic arm features a ball-and-socket joint that rotates 360Ā°, 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. The Leofoto AM-5/6 feature one end with an anti-twist 1/4th mounting stud and the other end a universal cold shoe adapter with a 1/4th mounting hole.
