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.
