The Systematic Head was designed to help photographers who shoot wildlife, sport and action photography using long and ultralong lenses. Long lenses require the smoothest possible head movements, exceptional locking capabilities, minimized drift angle, and fast, intuitive operation. The Systematic Head has a centre ball with a very large diameter, housed in an extremely low and compact profile, thanks to its revolutionary hydraulic locking system – located, for the first time, inside the ball itself. The locking collar moves with your equipment so you can always find and operate the head’s controls while keeping your eye to the view finder. Locking and applying friction are both operated using the same locking collar, which features a button that pre-set the base level of resistance of the locking collar.Because the head is designed for use with long lenses which have a tripod mount, this head does not need to rotate to the 90° portrait position. Portrait framing can be achieved by using the lens mount to rotate the camera.
