The PHD-66Q Revolver Head from Velbon is a 3-way head which utilizes a
unique shift feature when moving the mounted camera from the horizontal
position to the vertical position. The special revolving arm design
allows the camera and lens to maintain their position over the tripod
center column regardless of orientation.
The head and QB-635 II quick-release plate are manufactured from
magnesium alloy, making the head strong enough to support up to 12 lb,
while remaining light weight at just 1.4 lb. The head also features dual
leveling bubbles and an independent pan lock for 360° rotation.
