The auxiliary AF light of this camera conforms to the safety standard
(IEC60825-1) for Class 1 LED product. Looking at the light directly
will not create safety hazard. However, do not look into the emitter
from a very short distance since you may feel dazzled.
The camera does not emit the auxiliary AF light under the following
condition: the capture mode is set to C (Movie), H (Landscape) or
x (Candlelight), or the focus mode is set to pan focus, infinity mode,
or manual focus.
In the H (Landscape) and x (Candlelight) mode, however, you can
let the camera emit the auxiliary AF light by setting [Aux. AF Light]
to On.
