Note:
When AUTO is set, make sure to set the FREEZE item of the FREEZE screen to the
NORMAL.
Note:
This item cannot be set only when the FREEZE item on the FREEZE screen is
set to NORMAL. (not available with RANDOM, TRG, FLASH, SLOW SHUT).
The shutter speed is set to that at the FREEZE screen .
Note:
ALC can not be set when the FREEZE item of the FREEZE screen is set to
RANDOM TRG, Flash or SLOW.
Note:
When the shutter speed is increased, the light volume may not be high
enough. Therefore an adjustment of the lens’ iris or sensitivity is necessary.
Also, attention is required to the picture quality because the GAIN is boosted,
the sensitivity increases and causes a rough appearance to the picture.
The shutter speed can be varied when the SHUTTER is set to the V.SCAN or the
STEP.
Increase shutter speed: Press the DATA+ button.
Decrease shutter speed: Press the DATA- button.
It is recommended to set the RANDOM SHUT to 1/100 [U Ver.] or
1/120 [E Ver.]
in
the area with 50 Hz [U Ver.] or
60Hz [E Ver.]
to decrease flickers when an object is
shot under a fluorescent lamp.
