The Waterbird MS 150 Multislider is not your average camera slider. While some sliders are curved and others are straight, the Waterbird MS 150 is a 47.2 slider that can operate as either a straight or curved track. To curve the track, simply unlock the rails and set the curve radius to fit the desired composition. Each track segment has its own 1/4"-20 thread for supporting on stands or tripods. When combined with the separately available motor kit, the Waterbird MS 150 can be used to record innovative time-lapses and timed camera movements.
