A camera crane includes an arm having a back section, a middle section telescopically extendible into and out of the back section, and a front section telescopically extendible into and out of the middle section. A camera platform is pivotally attached at or near the front end of the front section. A counterweight is movable along the back section. An arm support can support the back section at two or more positions. Consequently the pivot axis of the arm can be shifted to the front or rear, to change rear clearance requirements, counterweight requirements, and the reach of the arm. An electronic controller is linked to a motor and a sensor on a camera head, with the motor acting to keep the head level.
