Safety shift
OFF: Disable
Tv/Av: 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.
ISO: 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
2: 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.162).
However, if the manually set ISO speed exceeds the [ Auto ISO range ],
the safety shift will take effect up or down to the manually set ISO speed.
Safety shift will take effect if necessary even when flash is used.
