Focusing functions
When you turn a focus ring to focus on a subject it’s called manual focus.
If you’re a beginner, it usually takes some time to get used to this style of
focusing. Fortunately, your digital camera provides not only manual
focus, but also auto focus and various other focus modes — all easily
accessible through simple button operations. These different modes will
enhance your shooting flexibility. For example, if you want to capture a
fast-moving subject without blur, choosing the right shutter speed is
important. But you can also use focusing to achieve the same effect —
when the focus mode is set to continuous AF mode, the camera focuses
on the subject in anticipation of its movement.
