C.Fn2: Exposure

Safety shift

C.Fn2

OFF: Disable
Tv/Av: Shutter speed/Aperture

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 the standard exposure.

ISO: ISO speed

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 the standard exposure.

When [

ISO speed

] is set, safety shift will also work with AEB shooting in

the <

a

> mode.

Under [

], even if [

Range for stills

shutter spd.

] is changed from the default setting, safety shift will

override it if the 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 range

] setting (p.167). However, if

the manually set ISO speed exceeds the [

Auto 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.

If [

ISO speed

] is set, the camera’s internal temperature is low, and the

safety shift sets the ISO speed to ISO 32000 or higher automatically, the
maximum continuous shooting speed will decrease (except when you use
AC Adapter Kit ACK-E4). For details, see page 148.
