The Cinetics CineSkates Pro Tabletop Dolly & Ballhead Kit
-- the dolly's wheels can be aligned and locked in matching positions, along ruler markings, to achieve specific rotations (or you can let the wheels loose). The ballhead completes the dolly, enabling panning and tilting of an attached camera. Employed patiently, the dolly, ballhead and an attached camera can pull off uninterruptedly fluid-rolling shots. If combined with carefully arranged set design and carefully selected sound and effects in editing, these shots can communicate emotion, strengthening hence your scenes.
The dolly and ballhead together support up to 11 lb camera loads, so you can attach a camera with a matte box on it if you want. The ballhead includes an x-shaped universal quick-release camera plate. You can keep the plate attached to a camera at all times and slide the camera on and off the ballhead as needed. The ballhead is made of aluminum.
