Wide-area AF is best for land- scapes and other subjects with large ele- ments.

■Normal-area AF. This mode uses smaller focus zones, and so is best suited for tri- pod-mounted images where the camera is held fairly steady. As with Wide-area AF, the focus zone will be outlined in red. You can move the focus zone around the screen with the multi selector buttons. When sharp focus is achieved, the focus zone box will turn green. (See Figure 6.4.)

■Subject-tracking AF. This mode allows the camera to “grab” a subject, focus, and then follow the subject as it moves within the frame. You can use this mode for sub- jects that don’t remain stationary, such as small children. When using Subject-track- ing AF, a white border appears in the center of the frame, and turns yellow when focus is locked in (as described in the section that follows). To activate focus or refo- cus, press the multi selector up button. I’ll explain Subject-tracking in more detail next. (See Figure 6.5.)

■Manual focus. In this non-automatic focus mode, you can move the focus area around the frame with the multi selector buttons, press the shutter release halfway, and then adjust focus manually by rotating the focus ring on the lens. When sharp focus is achieved, the red focus zone box will turn green, and the camera’s beeper, if enabled, will sound.
