2. The Basics of Autofocus
How autofocus works and why you should care
You don’t need to know how the autofocus in your camera works, but you should. Knowing what the camera is doing as it tries to autofocus allows you to help it along and, in doing so, get the best results. The autofocus in your camera is an amazing technology that photographers just take for granted now.
