Manual shutter speed adjustment
Avoid recording under fluorescent light, mercury
light or sodium light because the color and
brightness of the playback image may change.
If you increase the shutter speed manually, the
sensitivity lowers and accordingly the gain value
increases automatically, which may increase
the noises on the screen.
You may see vertical lines of light in the
playback image of a brightly shining subject or
highly reflective subject, but this is not a
malfunction.
During normal playback, image movement may
not look smooth.

When recording in an extremely bright place,
the color of the screen may change or flicker. If
this happens adjust the shutter speed manually
to 1/60 or 1/100.
Manual iris/gain adjustment
If the value does not become "OPEN", you
cannot adjust the gain value.
If the gain value is increased, the noise on the
screen increases.
Depending on the zoom magnification, there are
iris values that are not displayed.
Shutter speed range
1/60–1/8000 seconds: Tape Recording Mode

The shutter speed closer to 1/8000 is faster.
Iris/gain value range
CLOSE (Closed), F16, ..., F1.7,
OPEN (Opened) 0dB, ..., 18dB
Value closer to [CLOSE] darken the image.
Value closer to [18dB] brighten the image.
Values with dB are gain values.
Card slow shutter mode
If the shutter speed is set to 1/2, 1/4, 1/8, or
1/15, then the card slow shutter mode will be
activated.
If the [OFF/ON] switch or the mode dial is
operated, then the slow shutter mode will be
canceled.
In the slow shutter mode:
The white balance is fixed.
Focus in manually.
If the [AUTO/MANUAL/FOCUS] switch is set to
[FOCUS], then the shutter speed will
automatically be set to 1/60 and the subject is
focused in on. After that the previous shutter
speed will be restored. When the subject is
focused on, [MF] flashes.
If the scene is low in brightness or contrast, the
subject may not be focused in on.
While the Camcorder is focusing on the subject,
you cannot operate any control on it with the
exception of [OFF/ON] switch, mode dial,
[AUTO/MANUAL/FOCUS] switch and
[POWER LCD] button.
