Adjusting The Flange Focal Length - Sony scl-z18x140 Operating Instructions Manual

Adjusting the
Flange Focal
Length
After attaching the lens to the camcorder,
adjust the flange focal length (distance
between the lens mount attachment plane
and the imaging plane). The flange focal
length can be automatically adjusted by
pressing the F.f adjustment button of the
lens or by menu operation of the camcorder.
When automatic adjustment of flange focal
length is activated, focusing is performed
both at the wide-angle and telephoto ends of
the zoom for flange focal length adjustment
and the result is stored so that the in-focus
condition is maintained even if you change
the zoom position after focusing.
Notes
• If a subject of insufficient contrast is
used, or if the camcorder or subject
moves during the adjustment, adjustment
cannot be made properly. Once the
adjustment begins, do not touch the
camcorder body or lens until it ends.
• When "Setting" of the "Slow Shutter" of
the CAMERA SET menu is "On," be
sure to set it to "On" before starting the
adjustment.
• Be careful that no light source, such as a
lamp, the sun, or a bright window, is in
field of view during flange focal length
adjustment.
• If the adjustment screw of the camcorder
for flange focal length is rotated after
automatic adjustment of flange focal
length, the adjusted flange focal length is
shifted. Be careful not to rotate the
adjustment screw after automatic
adjustment.
