Auto focus is ideal for viewing mid to long-range but isn't designed for close-up observations. The best auto focus binoculars come with a wide depth of field, decent magnification and allow you to focus on anything from 30 feet to infinity. For convenience, we'll refer to auto focus, self-focusing, constant-focus, and permanently focused binoculars all as "auto focus binoculars." These binoculars are permanently focused by the manufacturer for medium distances (usually around 30 to 60 feet) to infinity.
