autofocusing

Camera sharpens itself

Autofocusing is the process by which a camera or optical device automatically adjusts its lens to bring a subject into sharp focus.

The term describes both the action and the technology: The autofocusing kicked in as soon as I pointed the camera.

It contrasts with manual focusing, where the user adjusts focus by hand.
