Chapter 3 Adjustments and Settings
The shutter modes that can be used with the
electronic shutter and the shutter speeds that can
be selected are listed below.
Standard mode
Select this mode for shooting fast-moving
subjects with little blurring.
You can set the shutter speed in one of two shutter
modes: Speed mode, in which the speed is set in
seconds, and Angle mode, in which the speed is
set in degrees.
Speed mode
a) This speed cannot be selected when the camcorder is
in Slow & Quick Motion mode and OPERATION
>Rec Function >Frame Rate in the setup menu is set
to a value that is greater than the system frequency.
Angle mode
180°, 90°, 45°, 22.5°, and 11.25°
ECS (Extended Clear Scan) mode
Select this mode for obtaining images with no
horizontal bands of noise when shooting subjects
such as monitor screens.
As shown in the following tables, the range of
shutter speeds that can be set varies depending on
whether the Slow & Quick Motion (S&Q)
function is on or off.
System lines: 1080
System lines: 720
SLS (slow speed shutter) mode
Select this mode for shooting subjects in low level
lighting conditions.
Notes
SLS mode cannot be used when the video format is SP
1440/23.98P or when the camcorder is in Slow &
Quick Motion mode.
It is not possible to output the color bar signal, turn the
SLS mode on or off, or change the number of
accumulated frames when the number of accumulated
frames is set to 16, 32 or 64.
Notes
When the automatic iris is used, the iris opens wider as
the shutter speed increases, thus reducing the depth of
field.
The selectable shutter speeds vary depending on the
current system frequency.
