2093121 9206034 PCTABS00011 A camera support (100) having a pedestal (101) separable from a dolly (102). The pedestal (101) has a gas-filled telescoping column (900) with a tapered driver cylinder (921) to provide a uniform load counterbalancing force with the column (900) at any position. Column braking (1200) and drive systems (1150) are provided as accessories. The dolly (102) has a belt and sprocket steering system (160) with a conventional steering angle corrector (300) having offset sprockets (312, 320). A shift apparatus for shifting the dolly steering between crab and conventional steering modes includes drive, crab, and conventional steering sprockets (186, 188, 194) engageable by shift pins (210, 212, 214) actuated through a shift fork (204) by a rocker (271) on top of the dolly deck. An electronic steering mode shifter accessory (800) automatically shifts the steering system between conventional and crab steering modes. A drive column (1300) for linking a steering wheel (252) to the dolly steering system (160) has a plurality of telescoping segments (1340, 1370, 1390, 1399) axially offset from each other with pulleys supporting cable loops (1382) protruding through the walls of the segments (1340, 1370, 1399).
