What is the difference between NORMAL and SMALL AF SENSITVITY?
NORMAL AF SENSITIVITY is used for most shooting situations. In this setting, the camera uses a focusing area (focusing point) that is slightly larger than the area indicated in the viewfinder. SMALL AF SENSITVITY focuses only within the selected AF area. This setting can be useful in situations such as wildlife photography where it is necessary to photograph animals through tree branches in the foreground. Using a more precise AF area will reduce the chance of the autofocus system becoming confused by the branches.
