Auto Focus

Abbreviated as AF, auto focus is a function of a digital camera in which the camera automatically focuses on the subject in the center of the LCD or viewfinder. Digital cameras come standard with auto focus, and more expensive models, or those considered professional digital cameras, will have the option to select the auto focus area, rather than just auto focusing in the center of the LCD or viewfinder.
