JVC GR-45 User Manual

Auto-focus
Manual focus
-Focu* detection zone
•A small area around the center of the
picture, which varies depending on
the zoom and focus conditions, is
used to detect focus. (No actual
indication provided on the screen.)
CAUTION
• Do not touch the focus ring while the auto-focus
mechanism is in operation.
• Be careful not to cover the auto-focus sensor
window, otherwise accurate focusing will not be
possible.
•When not in use, do not leave the VideoMovie in
the Autofocus mode with power on; otherwise light
entering the auto-focus sensor window will operate
the auto-focus mechanism, consuming power.
Correct focus may not be obtained in the following
situations. In such cases manual focusing should be
performed to obtain proper focus.

Note:
• If the lens and/or auto-focus sensor window are
smeared with staint or blurred with condensation,
accurate focusing is not possible. Keep them clean.
If they become dirty, wipe with a piece of soft
cloth. When condensation occurs, dry them by
wiping with a soft cloth or wait for conditions in
which they become dry.
One-hour recording
•To record longer on a single cassette, use the LP
(Long Play) mode.
• For LP recording, a higher-capacity battery pack
may be used.
• For worry-free shooting, it is recommended that
you prepare battery packs for 3 or 4 times the
length of time required for the intended recording.

Caution:
Convering the white balance sensor while manually
focusing will result in poor colour reproduction.
Note:
•When you use the manual focus mode, be sure to
focus the lens in the maximum telephoto position.
If you focus in on a certain subject in the wide-angle
position, sharply-focused images cannot be obtained
when zoomed up because the depth of field is re¬
duced at longer focal lengths.
