The Sirui G-10KX Ball Head allows you shoot panoramic shots and portraits with ease. It has an Arca-type quick-release plate and a special locking mechanism that enables the head to bear weights of up to 18 kg. Moreover, the locking mechanism has secondary safety-release button that prevents accidental disengagements. Dual bubble levels are incorporated in the design of the ball head for accurate horizontal leveling. Further, the ball head is made from aircraft-grade aluminum alloy that offers good resistance to wear, thanks to its anodized surface.
