The SIRUI ball heads are extremely precise and manufactured with the utmost care. The high quality of the tripod heads is guaranteed by high-end CNC milling and a high-quality surface coating. For the KII series, the tolerance between ball and bearing is maximum 0.01 mm. The K-20II head works precisely and smoothly. With its load capacity of up to 25 kg, it has your camera firmly in place. The base is rotatable by 360°, ideal for panoramic shots. The locking knob for the ball can be limited via a scale in the end stop. So you can adjust the movement of the head individually to your camera. For example, this prevents the ball from loosening too much and thus prevents the camera from tilting unintentionally. The safety lock system prevents accidental slipping of the quick-release plate.
