The Sirui K-30X Ball Head (Black) 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 interior ball locking of the K-30X 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 30kg. 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 & stability. The Arca-style platform conforms to standard sizes, so you can use compatible plates from other manufacturers.

The K-30X is CNC-machined from an aircraft-grade aluminium alloy and anodised with an oxidation treatment that ensures a durable, high-quality finish.

All Sirui products come with a 6-year warranty.
