Canon EOS 10D AF/AF lock, no AE lock, AE/AF, no AE lock, Emits/Fires, Does not emit/Fires

Custom Function Settings

2:AF/AF lock, no AE lock

In the AI Servo AF mode, you can press the < > button to stop the AF operation momentarily when there is an obstruc- tion passing in front of the camera. This prevents the AF from being thrown off. The exposure is set when the shot is taken.

3:AE/AF, no AE lock

This is useful for a subject that moves and stops repeatedly. In the AI Servo AF mode, you can press the < > button to start or stop the AI Servo AF operation. The exposure is set when the shot is taken. Thus, the optimum focusing and exposure are always ready for the decisive moment.

C.Fn-04 and C.Fn-17-0/1/2 (→p.151) both have AF start/ stop and AE lock functions. If you have set both of these Custom Functions and you execute both Custom Function operations, the latter operation will not work. The only exception is when AF stop is executed after AF start.
