Safety Shift - Canon POWERSHOT PRO1 User Manual

Setting the Aperture (continued)
Depending on the zoom position, certain aperture values may
not be available.
See page 206 for settings that can be changed in this mode.
Please note that camera shake becomes a factor at slow shutter
speeds. If the camera shake warning
monitor (or in the viewfinder), secure the camera to a tripod
before shooting.
In this mode, the shutter speed with synchronized flash is 1/60
second to 1/250 second. The aperture value setting may
therefore be changed automatically to match the synchronized
flash speed even if its value was set previously.

Safety Shift

If you set [Safety Shift] to [On] in the Rec. menu when the shooting
mode is Tv or Av, the camera automatically changes the shutter
speed or aperture value to obtain the correct exposure if
necessary.
The safety shift function does not work when the flash fires.
