Abstract
A camera crane arm has a frame pivotally supporting a central beam section. Outer beam sections are attached to and spaced apart from the central beam section. A leveling system is externally attached to the frame and pivotally linked to a camera platform, to maintain the platform in a level orientation, as the crane arm is pivoted up and down, to adjust camera lens height. The crane arm is formed of sections having vertically offset ends, to reduce sagging. The sections have a high moment of inertia but low weight, and can be assembled without force.
