Nikon SB-27 Digital Camera User Manual


 
Autofocus flash operation in dim light
(For AF SLR cameras only)
Nikon AF SLR cameras using AF Nikkor lenses can
autofocus in light as dim as a single candle. When ambient
light is insufficient for autofocus operation, the
SB-27's AF assist illuminator LED automatically turns ON to
give contrast to dark subjects, enabling the camera's
autofocus system to function when the shutter release
button is pressed halfway.
Take care not to block the AF assist illuminator LED.
The AF assist illuminator LED goes out as soon as the subject has been
correctly focused.
• No AF assist illuminator LED lights up if the F5’s, F100’s, F80-Series/
N80-Series’ or F65-Series/N65-Series’ central focus area is not selected.
Be sure to select the central focus area.
