I
Face Detection
AF
Gives autofocus priority to detected faces and
performs contrast autofocus. A yellow frame
appears for the main face (white frames appear for
other faces), and autofocus and automatic exposure
are performed for the main face. (default setting)
i Contrast AF
Displays Live View and performs autofocus based
on the information obtained from the image sensor.
S Phase
Difference AF
Cancels Live View and performs autofocus with the
AF sensor.
• It takes more time to focus on the subject when using I or i than when
using S. It is also difficult for the camera to focus on the following objects
(or under the following conditions).
- Objects with poor contrast
- Objects with no vertical contrast, such as horizontal stripes
- Objects with constantly changing brightness, shape, or color, such as a
water fountain
- Objects whose distance from the camera changes
- Small objects
- Objects appearing in both the foreground and background
- When using a special filter
- Objects at the edge of the screen
• If the shutter release button is pressed halfway during Live View when
[Autofocus Mode] is set to S (Phase Difference AF), the Live View image
will disappear and the autofocus system operates. Once focused, the Live
View image will be displayed again.
• The face detection is not performed when the focus mode is set to \
(except when in I (Auto Picture)).
• When [AF Mode] is set to k (Continuous mode), the built-in flash will not
discharge multiple times.
