Here's an innovative 3-D head unlike any other. Cast from lightweight magnesium, it's designed for use with 35mm SLRs and medium format cameras. It can be positioned virtually any way you like for exact framing of the image. The lock-system, using spring-loaded conical joints, allows greater flexibility than any other 3-D head, whether it is mounted on a tripod center column or lateral arm. The rubber grip knobs provide fingertip control. Supplied with a quick-release plate.
