Manual shutter speed adjustment
≥Avoid recording under fluorescent light, mercury 
light or sodium light because the colour 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 the extremely bright place, 
the colour of the screen may change or flickers. 
If so, adjust the shutter speed manually to 1/50 
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.
ª
Shutter speed range
1/50–1/8000 seconds: Tape Recording Mode
1/2–1/2000 seconds: Card Recording Mode
The shutter speed closer to 1/8000 is faster.
ª
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, 1/3, 1/6, or 
1/12, 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 
cancelled.
≥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 1/50 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 movie camera 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.
