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.

ªShutter 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.

ªIris/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.

ªCard 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.

MF

≥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.
