The compact professional Slik SBH-400AS ball head is a lightweight, low-profile head with an independent pan lock knob. The low-profile quick release plates may be left on the camera and won't hinder vertical shooting. The cam lock quick release system allows users to attach the camera from the top of the platform without sliding in or out of the grooves. Weighing just .6 lbs, the SBH-400AS ball head supports up to 8.8 lbs. of gear. The head is capable of handling a professional DSLR with standard lens. The head also has a separate lock with degree markings around the base for stitching together panoramic photos. The head to tripod connection is a standard U3/8" thread and comes with a U1/4 20" thread adapter to mount to your tripod legs of choice.
