8. Autofocus measuring flash
AF operating modes
Two operating modes are available with AF cameras (depending on the camera model):
•Focusing priority (One-shot AF):
The shutter can only be released when the subject has been sharply focused by the AF system. If the camera’s AF system is unable to focus sharply, then the shutter cannot be released and the flash cannot be fired.
k• Shutter release priority (AI Servo AF):
The shutter can always be tripped, irrespective of sharp focusing.
Shots may be blurred if the release is actua- ted before focusing has been completed by the camera.
The AF measuring flash is deactivated in this operating mode!
Please refer to your camera’s operating instructions for further details about the AF modes and their activation.
