Choose On to enable face priority (0 34).
When On is selected, the built-in AF-
assist illuminator will light to illuminate
poorly-lit subjects if:
• AF-S is selected for focus mode (0 155)
or single AF is selected in AF-A, and
• Auto-area or Single-point is selected
for AF-area mode (0 159).
The AF-assist illuminator will not light to assist the focus opera-
tion in advanced movie mode, during movie recording, or when
Off is selected. If the AF-assist illuminator does not light, autofo-
cus may not produce the desired results when lighting is poor.
