Sirui K-20X Overview
The Sirui K-20x Ball Head is an extremely sturdy head with control knobs for pan, tilt, and tension, plus an Arca-type 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.
The interior ball locking of the K-20x 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 55 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 & stability. The Arca-type platform conforms to standard sizes, so you can use compatible plates from other manufacturers.
The three control knobs 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 – there are degree markers at the panning base for panoramic photography.
The K-20x is CNC-machined from an aircraft-grade aluminum alloy and anodized with an oxidation treatment that ensures a durable, high-quality finish.
