Autofocus is a feature included on almost all cameras, and it has been that way for decades. We expect our cameras to be able to automatically focus on our subject quickly and accurately.

However, sometimes autofocus can fail. It might be that the camera just doesn't seem to want to focus at all. Or it might attempt to focus, but give up. Or it might tell you that it has focused, but the focus is actually somewhere else than where you wanted it.

In this article we'll look at ten reasons why autofocus may not work correctly, and what you can do to avoid / fix these problems.

Something that you may come across when browsing photography forums, or reading camera or lens reviews, is the mention of the camera or lens 'Front focusing' or 'Back focusing'. This means that the camera / lens focuses in front or behind of the subject, rather than where it should have focused. Obviously not a desirable trait.

In this article we'll look at what causes back and front focusing, how to check if your camera / lens suffers from it, and what you can do about it if it does.
