z Tips
• While recording a bright subject, diffraction
may occur if you close the aperture further
down, resulting in a fuzzy focus (this is a
common phenomenon with video cameras). The
ND filter D suppresses this phenomenon and
gives better recording results.
Adjusting the gain
You can adjust the gain manually when you
do not want to use the AGC (automatic gain
control).
1 Set the AUTO/MANUAL switch F to
MANUAL during recording or standby.
2 Set the gain switch H to H, M or L.
The gain value set for the selected gain
switch position appears on the screen.
You can set the gain value for each gain
switch position from [GAIN SETUP] of
the (CAMERA SET) menu
(p. 69).
To adjust the gain automatically
Press the GAIN button I, or set the
AUTO/MANUAL switch F to AUTO.
b Notes
• When you set AUTO/MANUAL switch F to
AUTO, other manually adjusted items (iris,
shutter speed, white balance) also become
automatic.
Adjusting the shutter speed
You can manually adjust and fix the shutter
speed. You can make a moving subject look
still or emphasize the movement of a
moving subject by adjusting the shutter
speed.
1 During recording or standby, set
AUTO/MANUAL switch F to
MANUAL.
2 Press the SHUTTER SPEED button E.
3 Change the shutter speed displayed on
the screen by turning the SEL/PUSH
EXEC dial G.
You can adjust the shutter speed in a
range of 1/3 second through 1/10000
second or the extended clear scan
( ).
The denominator of the set shutter speed
appears on the screen. For example,
[100] appears on the screen when you
set the shutter speed to 1/100 second.
The larger the value on the screen, the
faster the shutter speed.
4 Press the SEL/PUSH EXEC dial G to
lock the shutter speed.
To readjust the shutter speed, do steps
2 to 4.
z Tips
• When recording a subject such as a monitor
screen, set the shutter speed in the extended
clear scan ( ) range in order to obtain
images with no horizontal bands of noise. You
can set the shutter speed for the extended clear
scan from [ECS FREQ.] in the
(CAMERA SET) menu (p. 71).
To adjust the shutter speed
automatically
Press the SHUTTER SPEED button E
twice, or set the AUTO/MANUAL switch
F to AUTO.
b Notes
• When you set the AUTO/MANUAL switch F
to AUTO, other manually adjusted items (iris,
gain, white balance) also become automatic.
z Tips
• It is difficult to focus automatically at a lower
shutter speed. Manual focusing with your
camcorder attached to a tripod is recommended.
• The picture may flicker or change colors under
fluorescent lamps, sodium lamps, or mercury
lamps. You can reduce flickering by setting the
shutter speed to an appropriate frequency in the
extended clear scan (
([ECS FREQ.] p. 71).
