Using Face Detection
Shooting options
Tips for detecting faces
•  When your camera detects a face, it tracks the detected face automatically. 
•  Face Detection may not be effective when:
- the subject is far from the camera (The focus frame will appear orange for Smile 
Shot and Blink Detection.)
- it is too bright or too dark
- the subject is not facing the camera
- the subject is wearing sunglasses or a mask
- the subject’s facial expression changes drastically
- the subject is backlit or the lighting conditions are unstable
•  When you set Face Detection options, the AF area is automatically set to Multi AF.
•  Depending on the Face Detection options you selected, some Shooting options 
may not be available.
