Highly precise and heavy duty - maximum controlThe SIRUI ball heads are manufactured extremely precisely and with the utmost care. The high quality of the tripod heads is guaranteed by high-end CNC milling and a high-quality surface coating. In the KII series, the tolerance between ball and bearing is a maximum of 0.01mm.The K-10II head operates particularly accurately and smoothly. With its load capacity of up to 20kg, it has your camera firmly in its grip. The base can be rotated 360Adeg, ideal for panoramic shots. The locking knob for the ball can be limited via a scale in the end stop. This allows you to individually adjust the mobility of the head to your camera. This prevents, for example, too much loosening of the ball and thus an unintentional tilting of the camera. The Safety Lock System prevents the quick-release plate from accidentally slipping off. The clamping device for the quick release plate is compatible with the Arca Swiss system and allows the use of various plates. The K-20II head operates particularly accurately and smoothly.
