Notes About Target Finding AF
• Depending on shooting conditions, the subject that the camera determines to be the 
main subject may vary.
• The main subject may not be detected when using certain White balance settings.
• The camera may not detect the main subject appropriately in the following situations:
- When the subject is very dark or bright
- When the main subject lacks clearly defined colors
- When the shot is framed so that the main subject is on the edge of the screen
- When the main subject is composed of a repeating pattern

Notes About Face Detection
• The camera’s ability to detect faces depends on a variety of factors, including the direction 
in which the faces are looking.
• The camera cannot 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
C
Face Detection During Movie Recording

A129) in the movie menu is set to Face priority, the camera 
focuses on human faces during movie recording.

b (e) button is pressed when no faces are detected, the camera focuses on the area 
in the center of the frame.
