The Ulanzi U30S Universal Ball Head has a 1/4″-20 thread camera mount to hold photo and video accessories as well as compact and mirrorless cameras weighing up to 6 lb. The single-locking knob disengages, so you can move the ball at a 90° angle or rotate it 360°. The head is mountable with its interchangeable 1/4″-20 to 3/8″-16 socket, or with the included accessory foot that locks down by turning the thumb wheel against another shoe mount.
