The Crane 3-Lab gimbal supports up to two motors at the same time. The Zhiyun-Tech TransMount Focus & Zoom Servo Combo Kit includes the TransMount Max zoom/focus servo and slightly lighter TransMount Lite focus servo. Together these two motors allow you to control both focus and zoom with zero latency. The motors attach to the bottom of the Crane's baseplate without any tools using just the included brackets, rods, and thumbscrews.
