aFace priority

If the camera detects a face, it focuses on the face (“Shooting with Face Priority” ➝ A 106).

If the camera detects multiple faces, the camera focuses on the face closest to the camera. When shooting non-human subjects or when

framing the subject in such a way that a face cannot be detected, the AF area mode becomes Auto, and the camera automatically selects the focus area (up

to nine areas) containing the subject closest to the camera.

wAuto (default setting)

Camera automatically selects the focus area (one of nine) containing the subject closest to the camera. Press the shutter-release button halfway to activate the focus area.

When the shutter-release button is pressed halfway, the focus area selected by the camera will be displayed in the monitor (up to nine areas).

xManual

Choose the focus area from 99 areas in the screen.

This option is suited to situations in which the intended subject is relatively still and not positioned in the center of the frame. Rotate the rotary multi selector or press H, I, J or K to select one of 99 focus areas displayed in the monitor’s focus-area selection screen, and shoot.

To end focus-area selection and adjust the flash mode, macro mode, self-timer and exposure compensation settings, press the k button. To return to the focus-area selection screen, press the k button again.
