Dynamic Perception Stage Zero 3-axis Slider/Motion Control System. Includes 4' track, slide cart with motor, heavy duty ball head, pan with motor, tilt with motor, DP controller, high capacity battery and charger, soft carrying case. This a very reliable and useful motion control system. You can use just the slider itself, or add the pan/tilt unit. You can also use just the pan/tilt unit on a tripod without the slider, which we often do. This system will carry a Sony FS7 stripped down (camera, VF and small lens), or use our Sony a6500 , or your small-medium camera. You can shoot in video mode, or time-lapse stills mode. Just download the DP app to control the system from your smart Bluetooth device. We use an iPhone for this.
