Note: Reason for facing the camera down.
The Zoom-Lens unit has a moving lens inside. This moving lens
requires a tolerance (10 µm order) when starts to move.
Because of 1/4" CCD and x22 zooming ratio, the tolerance will
affect the focal point.
When adjusting the camera with the Lens facing down, the
tolerance will be always pulled downward by the gravity, which
makes it possible to adjust back focus as the best.
