camera’s AF-Assist Illuminator automatically turns on and enables autofocus
operation in a dark environment.
NOTE: Continuous use of the AF-Assist Illuminator

to protect the firing tube. The illumination restarts after a few moments. Also, when
the AF-Assist Illuminator is used repeatedly in a short period of time, be careful not to
touch the AF-Assist Illuminator lamp because it may become hot.

AF-S and AF-I) is used, subject is dark and centre
focus area is selected or Dynamic AF Mode with
