AF-assist illumination
When light is too low for normal autofocus operation, the SB-5000’s AF-
assist illumination enables autofocus photography.
• The SB-5000’s AF-assist illumination is compatible with the multi-point
AF system.
• AF-assist illumination cannot be used with non-CLS-compatible cameras
and COOLPIX cameras.
■
Notes on using the AF-assist illumination
• AF-assist illumination can be used if an AF lens is attached and the
camera’s focus mode is set to S (single-servo AF with focus priority),
AF-A, or AF.
• The effective flash-to-subject distance with AF-assist illumination is
approx. 1 m to 10 m (3.3 ft to 32 ft) for the center of the image with a
50 mm f/1.8 lens. The flash-to-subject distance varies depending on lens
in use.
• Suitable lens focal length is between 24 mm and 135 mm. Focus points
for each focal length in which autofocusing is possible are:
D5 camera focus points
24 – 49 mm
50 – 84 mm
85 – 135 mm
• AF-assist illuminator will not light up if the camera’s focus is locked or
the SB-5000’s flash-ready indicator does not come on.
• For details, see the camera user's manual.
