0: Disable
1: Shutter speed/Aperture
This takes effect in the shutter-priority AE (
s
) and aperture-priority AE
(
f
) modes. If the subject brightness changes and the standard exposure
cannot be obtained within the autoexposure range, the camera will
automatically change the manually-selected setting to obtain a standard
exposure.
2: ISO speed
This works in the Program AE (
d
), shutter-priority AE (
s
), and aperture-
priority AE (
f
) modes. If the subject brightness changes and the standard
exposure cannot be obtained within the autoexposure range, the camera
will automatically change the manually set ISO speed to obtain a standard
exposure.
Under [
z
3: ISO speed settings ], even if [ ISO speed range ] or [ Min.
shutter spd. ] is changed from the default setting, safety shift will
override it if a standard exposure cannot be obtained.
The minimum and maximum ISO speeds of the safety shift using the ISO
speed will be determined by the [
Auto ISO range ] setting (p.124).
However, if he manually set ISO speed exceeds the [ Auto ISO range ],
the safety shift will take effect up to the manually set ISO speed.
If [ Shutter speed/Aperture ] or [ ISO speed ] is set, safety shift will take
effect if necessary even when flash is used.
