PROBLEM TO BE SOLVED: To provide the tripod pedestal of a lens barrel, by which weight balance between the lens barrel and a camera body is adjusted finely. SOLUTION: The tripod pedestal 20 is provided with a positioning mechanism 13 of a ring-like member 12, coupled in manner of a helicoid with the fixed barrel 11 of the lens barrel 10 in the rotating direction of the member 12 and a pedestal 14 attached at the ring-like member. The tripod pedestal is rotated in the periphery of the fixed barrel in a state with the screw of the positioning mechanism being loosened, so that the ring-like member is moved in the optical axis direction. A screw hole 14b is moved, so that it comes nearly to the position of the center of gravity of camera body and the lens barrel, and the attaching screw of a tripod is screwed into the screw hole, so that the tripod pedestal is fixed at the tripod. The vertical position and the lateral position of the camera body are selected, and the positioning mechanism is screwed in, so that the lens barrel is fixed. Since the weight of the camera body is increased, when accessories (a motor-driven device and a stroboscope) are attached to the camera body, it is fixed at the tripod so as to make the position of the screw hole come near the side of the camera body, by causing the tripod pedestal to rotate in the periphery of the fixed barrel.
