The Sirui K-10x Ball Head is an extremely sturdy head with control knobs for pan, tilt, and tension, plus an Arca-style 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, and the quick-release plate features two pop-up pins that prevent camera twist when it's tilted 90 . There's also a video pin on the plate to keep camcorders from twisting.
