Setting the shutter mode/shutter speed
Switch the <SHUTTER> switch to set the shutter speed in the shutter mode.
The shutter speed in the synchro scan mode can be changed by the <SYNCHRO SCAN> button on the side.

→ [SHUTTER SPEED].
Once selected, the shutter speed is saved even after the camera is turned off.
1
Press the <SHUTTER> switch positioned at <OFF> towards <ON>.
[POSITION1] is enabled.
2
Press the <SHUTTER> switch from <ON> towards <SEL>, and repeat this operation until the desired shutter mode or shutter

NOTE
t Whichever shutter mode the electronic shutter is used in, the higher the shutter speed, the lower the sensitivity of the camera becomes.
t When the aperture is in the automatic mode, it will increasingly open and the depth of focus will become shallower as the shutter speed is increased.
t Under lighting conditions using fluorescent lighting or other discharge tube, horizontal stripes might appear on screen. If this happens, this can be
improved by adjusting the shutter speed.
t A subject that quickly crosses the camera may appear distorted when shot. This is due to the method applied for reading the signals from the pickup
device (MOS sensor), and is not a malfunction.
t Shutter mode is disabled while the digital super gain function is active.
