The Bogen-Manfrotto 468MGRC5 incorporates the same "world first" hydraulic
ball-locking system as the 468MG, and uses a short sliding "video" camera plate
to allow some front-back or side-to-side adjustment of the camera's position
above the head, which ensures that the load of the camera and lens is balanced
above the tripod's center of gravity for more secure usage (For even bigger
lenses or off-center loads, the 468MGRC3 model has a longer sliding plate for
more freedom of positioning).
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.
The 468MGRC5 is designed to meet the demands of professional photographers who
require a light weight head but at the same time being able to support heavy
camera loads up to 26.5 pounds! The 468MGRC5 borrows the popular features found
on Manfrotto's standard range of ball heads -- such as independent pan and tilt
locks with a 360-degree pan movement and +90 to -90 degree tilt movement.
To keep weight low, the head is made of magnesium; and to provide smooth
movements, the 1 1/4-inch aluminum ball is Teflon coated. The oversized ball
locking knob allows for easy control even when using gloves.
