Chapter 1. The 7D Top Ten List > Set Your Autofocus
7. Set Your Autofocus
Autofocus (AF) on the Canon 7D is extremely sophisticated and very easy to work with. It’s important to understand how to use all of the different autofocus modes in order to increase your chances of producing sharp, well-focused images. Here are the descriptions of each of the autofocus modes:
One Shot: Use this setting to focus on a subject that is not moving, like a person posing for a portrait.
AI Focus: Use this feature to focus on something that is not moving, and the focusing system will track the subject if it starts to move (pets or small children, for example).
AI Servo: Use this setting for subjects that are in motion. The focusing system will track the subject that falls in the focus area.
