The Sirui C-10 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 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.
The ball locking of the C-10 head is extremely strong thanks to the double-bevel locking system, which helps yield a high load capacity of 33 lb. 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.
The three separate controls allow a photographer to exercise extremely fine control over the orientation of the camera, whether it's a DSLR, medium-format camera or a camcorder. Pan, for instance, can be adjusted while the tilt stays locked, enabling precise movement that's measurable – there are degree markers at the panning base for panoramic photography.
The C-10 is CNC-machined from an aircraft-grade aluminium alloy and anodised with an oxidation treatment that ensures a durable, high-quality finish.
