Sirui K-30X OverviewThe Sirui K-30x Ball Head is an extremely sturdy head with control knobs for pan, tilt, and tension, plus an Arca-style 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, and the quick-release plate has a rubberized surface that prevents camera twist when its tilted 90°.The interior ball locking of the K-30x head has a sphere tolerance of 0.01mm, and its equipped with an orientation-memory locking dial. This helps yield a high load capacity of 66 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 heads overall security & stability. The Arca-style 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 its a DSLR, 35mm, medium-format camera, or even a camcorder. Pan, for instance, can be adjusted while the tilt stays locked, enabling precise movement thats measurable – there are degree markers at the panning base for panoramic photography.The K-30x is CNC-machined from an aircraft-grade aluminum alloy and anodized with an oxidation treatment that ensures a durable, high-quality finish.Arca-style quick-release clamp with secondary safety lockTwo bubble levels (horizontal and vertical) on the quick-release platform ensure that your framing hews to the horizon in either portrait or landscape orientationThe friction-control knob, integrated into the ball-locking knob, allows the operator to adjust the resistance of the balls movementQuick-release plate is aluminum alloy with a rubberized surfaceStainless steel camera screwIn the BoxSirui K-30x Ball HeadQuick-Release PlatePouchAllen KeyLimited 6-Year Manufacturer WarrantyKey SpecsHead TypeBall HeadBase Mount3/8"-16 FemaleCamera Mounting Screw1/4"-20 MaleQuick Release Plate TypeArca-TypeFriction ControlYesLoad Capacity66 lb / 30 kgWeight1.1 lb / 0.5 kgHeadHead TypeBall HeadBase Mount3/8"-16 FemaleCamera Mounting Screw1/4"-20 MaleQuick Release Plate TypeArca-TypeNumber of Bubble Levels2Friction ControlYesIndependent Pan LockYesBall Sphere Diameter1.73" / 44 mmPan & Tilt RangePanning Range360°GeneralLoad Capacity66 lb / 30 kgWeight1.1 lb / 0.5 kgPackaging InfoPackage Weight1.575 lbBox Dimensions (LxWxH)6.1 x 4.9 x 3.8"
