The XPRO Ball Head with Q6 Arca-Swiss compatible camera plate is lightweight and strong, weighing only 520g but capable of supporting 10kg. The new ball locking system uses three wedges which enclose the ball entirely, which prevents movement and guarantees positional stability when locking the ball. A friction control and a bubble level for each plane of movement allows small movements of the camera to be made to allow precise positioning before locking. Polymer rings are used within the ball housing to lubricate movement, so no grease is used, avoiding leaks in hot conditions. The clamp is Arca-Swiss compatible and comes with a 70mm MSQPL6 camera plate. Unlike most Arca-pattern clamps, where the plate is slid in from one end and then locked, the Manfrotto ‘Top Lock’ design allows the plate to be inserted from above, where it engages with a snap security lock which can then be fully tightened with a short turn of the side knob.
