SHUTTER UP/SHUTTER DOWN button
Using the [SHUTTER UP] / [SHUTTER DOWN] button, the
following setting is possible: 1/60, 1/100, 1/175, 1/250, 1/375,
1/500, 1/1000, 1/2000, 1/4000, 1/10000.
Enabled only when [GAIN] switch
1
is set to [MANUAL].
Flicker-free mode
Prevents flickering caused by fluorescent lighting in area with
50 Hz.
When the shutter speed is set at 1/100 sec (flicker-free
mode), flickering is eliminated.
When looking at the picture on the monitor while the
electronic shutter is being used, the object movement
appears to be discontinuous.
For example: in shutter speed of 1/2000 sec. Since the
image for 1/2000 sec is taken out every 1/60 sec, this
phenomenon occurs.
When high-speed shutter is used, light may not be suffi-
cient.
