"The 468MGRC2 incorporates the same ""world first"" hydraulic ball-locking system as the 468MG, and uses Manfrotto's popular RC2 Rapid Connect Plate, which is small and light enough to leave permanently attached to your compact or SLR camera even when not using a tripod. Using hydraulics instead of a mechanical system produces a super-tight lock froma minimal turn of the locking knob, without sacrificing the smoothness of the ball's movement when unblocked. The 468MG series is designed to meet the demands of professional photographers who require a light weight head but at the same time being able to support heavycamera loads up to 35lbs! The 468MGRC2 borrows the popular features found on Manfrotto's standard range of ball heads - such as independent pan and tilt locks with a 360� pan movement and +90� / -90� tilt movement. 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. The 468MGRC2 also has a graduated engraved panoramic base.|Hydraulic system to lock the ball mechanism in place|Oil pressure against ball locks more firmly than mechanical methods|Calibrated adjustable friction control|Friction dial prests oil pressure when ball is unlocked to give easier framing adjustment and better safer support for heavy and long equipment|Ball lock knob compresses oil in compartment, exerting more locking force with minimum movement|Small and light RC2 Rapid Connect Plate w/QR Plate|Able to support camera loads up to 22lbs|Independent Pan Lock with a 360� Pan Movement|Independent Tilt Lock with a +90� / -90� tilt movement.|Head made of magnesium to provide smooth movements|2"" Aluminum Ball Teflon coated|Oversized ball locking knob allows for easy control|Graduated engraved panoramic base|Available in Various Plate type versions"
