The DJI Osmo Z-Axis is a spring-loaded stabilizing arm designed to reduce vertical shaking when walking or jogging with the DJI Zenmuse X3 Gimbal and Camera. The gimbal and camera assembly attach to the top of the Z-Axis arm, while the Osmo Handle secures at the bottom. The handle can be adjusted vertically for optimal positioning, providing enhanced stabilization for smoother shots during movement.
