AF-assist illumination will be used to assist the focus operation when the subject is poorly lit. The illuminator has a range of about 1.9 m (6 ft. 2 in.) at the maximum wide-angle position and 1.1 m (3 ft. 7 in.) at the maximum telescopic position.
However, the AF-assist illumination will not turn on in some scene modes even if Auto is selected (A36-41).
