Enables spot metering linked to the selected AF point. With automatic
AF point selection, spot metering will be at the viewfinder center.
C.Fn I -8 Safety shift
0: Disable
1: Enable (Tv/Av)
This works in the shutter-priority AE (Tv) and aperture-priority AE (Av)
modes. When the subject’s brightness changes erratically and the
correct autoexposure cannot be obtained, the camera will change the
exposure setting automatically to obtain a correct exposure.
2: Enable (ISO speed)
This works in the Program AE, shutter-priority AE, and aperture-priority
AE modes. When the subject’s brightness changes erratically and the
correct autoexposure cannot be obtained, the camera will change the
ISO speed within 100 - 1600 automatically to obtain a correct exposure.

If 2 is set, the maximum burst during continuous shooting (p.54) will
decrease. However, depending on the ISO speed during shooting, the
actual maximum burst might be higher than indicated in the viewfinder.
Even if the settable ISO speed range has been changed with C.Fn I -
3,12/13, the safety shift will override it when necessary to obtain the
correct exposure.
With settings 1 and 2, safety shift also works with flash.
