The 47.2 Motorized Parallax Slider from CAME-TV allows you to track a subject within the center of your shot or create a wide panoramic effect either manually or via the Bluetooth app. The rate of the panning effect is easily tuned at the end of the rail. The aluminum carriage is fitted with precision bearings that move smoothly and quietly along the rails. This slider can be used on a table or the ground via the adjustable feet and can be mounted to a tripod or stand with either a 3/8"-16 or 1/4"-20 screw. It is powered using the included NP-F750 battery.
