While some of the least expensive digital cameras have only automatic focus,  most SLR digitals offer three different focus modes:  manual, single auto focus and continuous auto focus, meaning the camera does all the work on bringing your subject into the best possible focus .All three of this will be addressed there.

The camera stays out of the focus equation and you, the photographer, make all the decisions regarding this, with manual focus .  This is done actually using an attached focusing ring that rotates on the camera lens or by setting different buttons.  This is the best focus mode, for those who like to have complete creative control of the finished product.

The camera automatically focuses when you press the shutter button either all the way down to shoot a photo or half way down to lock the focus in single auto focus mode .These mode is useful when shooting static objects.

In continuous auto focus the camera continuously focuses on the objects in the photo.In these mode the camera continuously corrects the focus as the objects distance from the camera changes. This mode is useful when you shoot photos of moving objects such as a race car during a race or airplanes during an air show . You can hold the shutter button half way down and continuously moved the camera to follow the object. A camera will continuously keep the object in focus.

Like any other feature automatic and manual focus modes have their pros and cons. How they work and what they were designed for, that is the first step to using them to your advantage is to understand . And then to experiment shoot photos using different focus modes and different types of objects and see how the camera behaves, that is the next step . Once you have done that you will be ready to use instinctively the best focus mode for each photo situation.
