DContinuous-servo Autofocus

In AF-Cmode or when continuous-servo autofocus is selected in AF-Amode, the camera gives higher priority to focus response (has a wider focus range) than in AF-Smode, and the shutter may be released before the in-focus indicator is displayed.

AGetting Good Results with Autofocus

Autofocus does not perform well under the conditions listed below. The shutter release may be disabled if the camera is unable to focus under these conditions, or the in-focus indicator (I) may be displayed and the camera may sound a beep, allowing the shutter to be released even when the subject is not in focus. In these cases, focus manually (0 62) or use focus lock (0 60) to focus on another subject at the same distance and then recompose the photograph.
