What is auto focus?
Asked on: 14 Aug 2009
Auto focus is the process whereby a camera automatically works out the focus without you having to manually change the setting of the lens.
Most cameras these days have autofocus whereby they send a beam and time how long it takes to come back, and thus know how far away the object you want to take a photo of is.
