A camera crane has a boom arm pivotably connected to a post assembly. A track section is pivotably attached to the front end of the boom arm, and is leveled via leveling rods. The boom arm has a joggled section to provide clearance for a camera operator. A camera frame carrying a camera is linearly moveable along the track section. Pivot joints provide for adjustable drag on pivoting movement, without backlash or slip/stick movement.
