• 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 (

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.
