
With the Micro-Stepping Control Technology, the video looks very natural at high zoom magnification during a jog
operation on a controller since the camera can be controlled by 0.05/sec. Hence it is very easy to make the camera
focus on desired target views at high zoom magnification. Additionally it is easy to make the camera focus on
desired positions with zoom-proportional pan/tilt movement.
