Using AF to Focus
If the focus is way off, face detection will not be possible. If the lens enables manual focusing even while the lens focus mode switch is set to <f>, turn the focusing ring to attain rough focus. The face will then be detected and <p> will be displayed.
An object other than a human face might be detected as a face. Face detection will not work if the face is very small or large in the picture, too bright or too dark, titled horizontally or diagonally, or partially hidden.
The <p> focusing frame might cover only part of the face.
When you press <9> straight down, the AF mode will switch to the Live mode (p.117). You can tilt <9> to move the AF point. If you press <9> straight down again, it will switch back to Liveu(face detection) mode. Since AF is not possible with a face detected near the edge of the picture, the <p> will be grayed out. Then if you press the <p> button, the center AF point <> will be used to focus.
