AF-Assist Illuminator
When the subject is dark and the shutter release button is pressed lightly,
the camera’s AF-Assist Illuminator automatically turns on and enables
autofocus operation in a dark environment.
NOTE: Continuous use of the AF-Assist Illuminator
When the AF-Assist Illuminator is used continuously, illumination is limited
temporarily 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.
Cancelling AF-Assist Illuminator
AF-Assist Illuminator automatically turns on in
the conditions mentioned on the previous
page. To cancel AF-Assist Illuminator (i.e.,
when the subject feels the illumination is too
bright), lightly press the shutter release button
while pressing the AF-Assist Illuminator cancel
button. However, the correct focus may not be
achieved without AF-Assist Illuminator.
