The Sirui G-20X Ball Head is an extremely sturdy head with separate control knobs for pan, tilt, and tension, plus an Arca-style clamp for the included quick-release plate. The ball locks down extremely tightly thanks to the double-bevel locking system which allows support of cameras up to 44 lb and safe 90° tilting for portrait orientation. The quick-release clamp features a secondary release button that prevents any inadvertent disengagement of the camera/plate from the clamp, thereby adding to the head's overall security and stability.
Three separate controls (pan, tilt and lock) 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. Pan, for instance, can be adjusted while the tilt stays locked, enabling precise movement that's measurable via degree markers for panoramic photography at the panning base.
The G-20X uses Computer Aided Manufacturing and an aircraft-grade aluminum alloy with a custom anodized surface treatment to ensure a durable, high-quality finish.
