This ball-and-socket tripod head has a pistol-grip-style handle that enables you to quickly put your camera into almost any position, and it locks firmly once the trigger is released. The pistol grip itself can be fixed in eight different positions to suit your shooting style. It is easy to adjust the level of friction on the ball head to accommodate heavier camera and lens combinations. Photographers who enjoy shooting panoramas will appreciate the 72-click head rotation, designed to space pictures 5 degrees apart, that makes the process of creating a joiner easier and more accurate. This is a versatile accessory that is very well made and extremely useful.
