To focus on the eyes of an animal or a bird
Set [ Face/Eye Subject] to [Animal] or [Bird] before shooting.
If the detection target is an animal or a bird, eyes can be detected only when shooting still images. Faces of animals and
birds are not detected.
Note
The [Eye AF] function may not function very well in the following situations:
When the person is wearing sunglasses.
When the front hair covers the person's eyes.
In low-light or back-lit conditions.
When the eyes are closed.
When the subject is in the shade.
When the subject is out of focus.
When the subject is moving too much
There are also other situations in which it may not be possible to focus on the eyes.
When the camera cannot focus on human eyes, it will detect and focus on the face instead. The camera cannot focus on eyes
when no human faces are detected.
The camera may not detect faces at all or may accidentally detect other objects as faces in some conditions.
