A camera supporting assembly includes a frame supporting interchangeable camera mounts thereon to support smartphones, and other camera enabled devices interchangeably thereon. A grip member with a first pivot coupling selectively couples to a second pivot coupling on the frame and a pair of stabilizer legs are suspended below the frame so as to balance the camera on the grip member. Wheel assemblies are selectively mounted on the stabilizer legs for alternate use in a portable dolly mode. Each wheel assembly is mounted by a spindle which is movable between different mounted positions corresponding to different angular orientation of the wheel axis relative to the frame to controllably steer movement of a camera supported on the assembly in the dolly mode without a track necessarily being provided.
