Autofocus

Auto Focus is a setting on a camera that decides what the Camera focuses on. You can either use single-shot or continuous focus, which is ideal for stationary and moving objects, respectively. When you have AutoFocus enabled, slightly pressing the shutter release will allow the Camera to focus on the object. If autofocus is not enabled, you must alter the focal point manually until your object or a portion of the image that you wish to sharpen comes into focus.
