What should I do if the autofocus of digital camera is not clear?

To eliminate it, we must first understand the reasons. Generally speaking, objects with dark surface, objects with too strong luster or reflected light, objects with too small contrast, fast moving objects, and objects with one part close to the camera and the other part too far away are more likely to cause this situation, such as white walls, water surfaces and glass. When shooting an object with the above characteristics, it is best to use manual zoom. In addition, after a long period of still shooting, the autofocus motor will appear "inertia", and the camera may not be able to focus clearly when moving to shoot other objects. At this time, as long as you press the push-pull button to zoom quickly or move the camera, you can start the focus motor and focus automatically.
