3 Custom Function SettingsK C.Fn-6 Auto AF point selection: Color Tracking Use this function to autofocus by recognizing colors equivalent to skin tones. This function works in One-Shot AF mode when the AF area selection mode is set to Zone AF (manual selection of zone) or 19-point AF auto selection. 0: One-Shot AF only In One-Shot AF mode, the camera selects AF points automatically based on AF information and information on colors equivalent to skin tones. This makes focusing on people easier, so you can prioritize composition in shooting. 1: Disable AF points are automatically selected based only on AF information. Generally, the nearest subject will be focused on.  With setting 0, focusing will take slightly longer than with setting 1.  Even with setting 0, the expected result may not be obtained depending on the shooting conditions and subject.  Under light so low that the flash emits the AF-assist beam automatically, AF points are selected automatically based only on AF information.
