4-2 Setting the Electronic Shutter
This section provides a description of the electronic shutter,
together with setting and handling directions.
4-2-1 Shutter Modes
The table below shows the shutter modes and speeds for the
electronic shutter provided in your AJ-SPX900E.
<Notes>
z In any mode, the higher the shutter speed the lower the
sensitivity of the camera.
z When the iris is automatically adjusted, the higher the shutter
speed the larger the iris, and the shorter the depth of focus.
4-2-2 Setting the Shutter Mode and Speed
The shutter speed in any shutter mode is set using the
SHUTTER switch.
In SYNCHRO SCAN mode, shutter speed can be switched
easily, using the synchro-scan adjustment switches (+/–) on the
side panel.
Note that the range of selectable shutter speeds may be pre-
defined; whether or not to use the SYNCHRO SCAN and
SUPER V modes may be determined through the <SHUTTER
SPEED> and <SHUTTER SELECT> screens. These screens
are accessible through the menu on the CAM OPERATION
page.
The selected shutter speed is retained even if the AJ-SPX900E
is turned off.
1 Press the SHUTTER switch, positioned at [ON], towards
[SEL].
2 Once more, press the SHUTTER switch towards [SEL].
Repeat this switchover until the desired mode or speed
appears in the viewfinder screen.
If all modes and speeds are available, the display changes
in the following order:
<Note>
Your AJ-SPX900E is not factory-set to display the SUPER
V mode on the viewfinder screen. To display this mode, set
the menu option SUPER V found in the <SHUTTER
SPEED> screen, which is accessible from the CAM
OPERATION page, to “ON”.
