Notes on Face Priority Tracking
• Only one subject can be tracked. If the camera detects multiple faces at the same time, the face
closest to the center of the frame is tracked.
• When the frame includes more than one face, the face detected by the camera and registered as
the subject to be tracked depends upon a variety of factors, including the direction in which the
faces are looking.
• Depending on shooting conditions, such as whether or not the subject is facing the camera, the
face may not be detected properly. Additionally, the camera may be unable to detect faces in the
following situations:
- When faces are partially hidden by sunglasses or otherwise obstructed
- When faces take up too much or too little of the frame
• When the camera is unable to track the registered subject, press the k button to track again, or
set
Face priority tracking to Off, frame the picture so that the subject is inside the border in the
center of the frame, and press the k button to register the subject again.
Image mode
Choose the image mode (combination of image size and compression rate) at which
images are saved (
A 38).
Changes made to the image mode setting are applied to all shooting modes.
Autofocus mode
Allows you to set the
Autofocus mode (A 50) used for subject tracking mode (the
default setting is
Full-time AF).
When using subject tracking mode while set to
Full-time AF, the camera
continuously focuses once a subject is registered for subject tracking until the
shutter-release button is pressed halfway to lock the focus. The sound of the camera
focusing will be heard.
Changes made to the autofocus mode setting in this mode will not be applied to the
autofocus mode setting in the A (auto) mode. The autofocus mode setting applied
in the subject tracking mode is stored in the camera’s memory even after the camera
is turned off.
Face priority tracking
When
On (default setting) is selected and the camera detects a human face, that
person is automatically registered as the subject to be tracked, and subject tracking
begins tracking that subject.
