Notes
• Whatever the operating mode of the electronic shutter,
the sensitivity of the CCD decreases with increasing
shutter speed.
• When the automatic iris is used, the iris opens wider as
the shutter speed increases, thus reducing the depth of
field.
• Under artificial light, particularly fluorescent or mercury
lamps, the light intensity may appear to be constant, but
the red, green, and blue intensities are actually changing
in synchronization with the frequency of the power
supply causing flicker. Using an electronic shutter under
such lighting could make the flicker even worse. Color
flicker is particularly likely to happen when the power
supply frequency is 60 Hz. However, if the power
frequency is 50 Hz, setting the shutter speed to
reduce this flicker.
• When a bright object is shot in EVS or ECS mode in
such a manner that it fills the screen, the upper edge of
the picture may have poor quality because of an inherent
characteristic of CCDs. Before using EVS or ECS mode,
check the shooting conditions.
You can turn on or off the EVS mode on the SW STATUS
page of the PAINT menu.

To select the shutter mode and shutter
speed
Use the SHUTTER switch to select a shutter mode or a
standard-mode shutter speed. To set the shutter speed in
ECS or SLS mode, with the SHUTTER switch set to ON
and the ECS or SLS mode selected, use the MENU knob
for adjustment.
You can use the SHT ENABLE page of the OPERATION
menu to narrow the range of choice in advance, or to select
in advance whether or not you use ECS/SLS mode.
To set the shutter mode and standard mode
shutter speed
Once the shutter speed is selected, it is retained even when
the camcorder is turned off.
