"The X-PRO 3-Way Head is Manfrotto's most compact, precise and reliable 3-way photographic head.The compact closed size that makes the X-PRO so easy to pack and carry is down to its retractable levers that can be extended when needed. With the levers retracted and folded for transport, the space occupied by the head is only 13 cm x 13.5 cm x 13.5 cm (5.1" x 5.3" x 5.3"). Friction controls on the X-PRO 3-Way Head's tilt and portrait axes help balance the weight of camera equipment so that fine framing adjustments can be made with the locking knobs open, only locking everything down once everything's ready. And with 3 leveling bubbles on the head, composition can be leveled precisely in-camera, reducing post production work, sturdily built with a rugged aluminum body for reliability and durability, the X-PRO supports up to 8 kg."
