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.

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:

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”.
