The Sirui K-20x Ball Head is an extremely sturdy head with control knobs for pan, tilt, and tension, plus an Arca-type clamp for the included quick release plate. The pan, tilt, and quick release knobs are all separate, while the tension knob is integrated into the ball-locking (tilt) knob. The head tilts 90 for portrait orientation. The three control knobs allow a photographer to exercise extremely fine control over the orientation of the camera, whether it's a DSLR, 35mm, medium-format camera, or even a camcorder.
