Notes
• If you use a subject with insufficient contrast, or move
the camcorder or subject during adjustment, this will
cause an adjustment error.
• Place the subject (the flange focal length adjustment
chart) so that it appears at the center of the screen at the
telephoto end. Arrange so that no nearby object (no
object closer to the camera than the chart) enters the
screen at the wide-angle end.
