The FB-36III Ball Head with Screw Knob Clamp from Sunwayfoto is a 3.2" tall, CNC-machined aluminum support with a load capacity of 40 lb. The head's main locking lever controls the movement of the ball; tension can be added or decreased as needed. The 10.7 oz head has a cut notch on the side that allows you to position the camera, which mounts via the Arca-type quick release system, at a 90° angle. The independent panning lock disengages, so you can rotate the head a full 360°. Scales are laser engraved at the base and at the top of the clamp for repeated setups, and the head mounts to a tripod via its 3/8"-16 threaded socket. A reducer bushing is included for tripods with a 1/4"-20 head mount.
