The Manfrotto 468MGRC2 is designed to meet the demands of professional photographers who require a light weight head but at the same time want to support heavy camera loads up to 22 lb.
The 468MG series uses a hydraulic system to lock the ball mechanism in place. Using hydraulics instead of a mechanical system produces a super-tight lock from a minimal turn of the locking knob, without sacrificing the smoothness of the ball's movement when unblocked. To keep weight low, the head is made of magnesium; and to provide smooth movements the 2" aluminum ball is Teflon coated. The oversized ball locking knob allows for easy control even when using gloves.
This head further offers a range of handy features: independent pan and tilt locks with a 360° pan movement; +90/-90° tilt movement; a graduated engraved panoramic base; and a calibrated adjustable friction control on the main knob.
The 468MGRC2 version uses the popular RC2 (3157N) quick release system, which is small and light enough to leave permanently attached to your compact or SLR camera even when not using a tripod.
