Abstract: A camera supporting tripod is described with a hip to which legs are attached. The legs are adjustable as to length. In addition, the tripod includes a center shaft mounted to the hip for tilting movement. The center shaft is also adjustable as to length. Manually actuated hydraulic mechanisms are provided for releasably holding the legs as to length, for releasably locking the center shaft to the hip to prevent relative tilting, and for releasably holding the shaft at the length to which it is adjusted. An instrument supporting head on the tripod includes friction brake panning and tilting mechanisms designed to apply a variable drag to these motions and also for smooth operation.
