Chapter 3 Adjustments and Settings for Shooting
SLS (slow speed shutter) mode
Select this mode for shooting subjects in low level
lighting conditions.
Notes
• SLS mode cannot be selected when SCAN
MODE is set to 23.9P.
• 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 1/100 can reduce this flicker.
• When a bright object is shot in 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 ECS mode, check the shooting
conditions.
• The selectable shutter speeds vary depending on
the current system frequency.
Switching the shutter mode, and the shutter
speed in standard mode: Repeatedly flick
the SHUTTER selector to the SELECT side
(see the next section).
Switching the shutter speed in ECS mode and
SLS mode: Select ECS mode or SLS mode
with the SHUTTER selector, and then turn
the MENU knob (see page 62).
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 or SLS.
To set the shutter mode and standard-
mode shutter speed
Once the shutter speed is selected, it is retained
even when the camcorder power is turned off.
1 Follow the procedure described in
“Selecting the display items” on page
171 to set the VF DISPLAY MODE
item to “2” or “3” on the VF DISP 1
page of the USER menu.
2 Flick the SHUTTER selector from ON
to SELECT.
The current shutter setting indication appears
for about 3 seconds in the setting change and
adjustment progress message display area of
the viewfinder screen.
Examples: “: SS : 1/250”, “: ECS : 60.0 Hz”
3 Before the shutter setting indication
disappears, flick the SHUTTER
selector down to SELECT again and
