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.
