Selecting the AF Mode
The AF modes available are [Live mode], [u Live mode] (face detection,] and [Quick mode]. If you want to achieve precise focus, set the lens focus mode switch to <MF>, magnify the image, and focus manually
Select the AF mode.

The image sensor is used to focus. Although AF is possible with the Live View image displayed, the AF operation will take longer than with the Quick mode. Also, achieving focus may be more difficult than with the Quick mode

If the focus is far off, face detection will not be possible. If the lens enables manual focusing even while the lens focus mode switch is set to <AF>, turn the focusing ring to attain rough focus. The face will then be detected and
will be displayed.
An object other than a human face may 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
focusing frame may cover only part of the face.
When you press <
> straight down or press <

> straight down again or press <
> to return to the u (face detection) Live mode.
Since AF is not possible with a face detected near the edge of the picture, the

AF operation
Focusing will take slightly longer.
Even when focus has been achieved, pressing the shutter button halfway will focus again.
The image brightness may change during and after the AF operation.
If the light source changes while the Live View image is displayed, the screen may flicker and focusing may be difficult. If this happens, exit Live View shooting and autofocus under the actual light source.
If you press the
button in the Live mode, the image will be magnified at the AF point. If focusing is difficult in the magnified view, return to the normal view and autofocus. Note that the AF speed may differ between the normal and magnified views.
If you autofocus in the Live mode’s normal view and then magnify the image, the focus may no longer be correct.
In the
Live mode, pressing the
button will not magnify the image
In the Live mode or
(face detection) Live mode, if you shoot a peripheral subject and it is slightly out of focus, aim the center AF point over the subject to focus, then take the picture.
The external Speedlite will not emit the AF-assist beam. However, if an EX-series Speedlite (sold separately) equipped with a LED light is used, the LED light will turn on automatically for AF-assist when necessary in the Live mode and
(face detection) Live mode.
