Hint
Setting [ Sbj Recog Frm Disp.] to [On] makes it easier to check the detection status of faces or eyes, etc.
[Subject Recognition AF] using a custom key is convenient in the following cases.
When you want to temporarily use [Subject Recognition AF] on the entire screen only while pressing the key, regardless of the [
Focus Area] setting
When you do not want to perform auto-focusing when the camera does not recognize a subject
Positioning the entire subject in the angle of view makes the subject easier to recognize.
Note
It may be difficult to focus on the subject in the following situations:
In low-light or back-lit conditions.
When the subject is in the shade.

When the subject is moving too much, etc.
It may be difficult to focus on eyes in the following situations even when the camera recognizes eyes:
When the eyes are closed.
When the eyes are covered by hair, etc.
When the person is wearing sunglasses.
There are also other situations in which it may not be possible to focus on the subjects.
When the camera cannot focus on the part you want to prioritize, such as the eyes of the subject, the camera may automatically
focus on other recognized parts such as the head or body of the subject.
Even when a white subject recognition frame is displayed around the subject's face, etc., the camera may automatically focus on
the part you want to prioritize, such as the subject's eye.
The subject may not be recognized when only a part of the subject is within the angle of view.
When only the hands and feet of a person or animal are visible
When a part of the subject is hidden and cannot be seen, etc.
The camera may accidentally recognize other objects as the designated subject under some conditions.
