Sirui K-40X Ball Head

The Sirui K-40X 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. There's also a video pin on the plate to keep camcorders from twisting. The interior ball locking of the K-40X head has a sphere tolerance of 0.01mm, and it's equipped with an orientation-memory locking dial. This helps yield a high load capacity of 77 lb.
