The Photo Clam PC-44NS Ball Head features extremely strong ball-locking for a remarkably high 110 lb load capacity. The head features separate knobs for locking the ball and the pan base, enabling you to keep the orientation of your framing locked while you pan. This makes it appropriate for panoramic photography.
Within the ball-locking knob there's a dial for applying progressive biaxial friction, to accommodate lighter and heavier camera setups across the head's vast load capacity.
The head features a slot for tilting 90° to portrait orientation. Bubble levels allow you to ensure that your framing hews to the horizon in either landscape or portrait orientation. Featuring a sturdy knob for its clamp, the Arca-style quick-release platform is compatible with camera plates (sold separately) from Photo Clam as well as other manufacturers such as Kirk, Arca-Swiss, and Really Right Stuff.
