Caution
The auxiliary AF light of this camera conforms to the safety standard
(IEC60825-1) for Class 1 LED products. Looking at the light directly will not
create safety hazard. However, do not look into the emitter from a very short
distance as it may make you dizzy.
Memo
The auxiliary AF light is not activated when the shooting mode is set to C
(Movie), or the focus mode is set to 3 (Pan Focus), s (Infinity), or \
(Manual Focus).

Setting the Sensitivity
Auto The optimal value is automatically selected from 80, 160, 320, or 400.
80
The lower the sensitivity, the less noise that affects the image. However the
shutter speed will be slower in low light conditions, so that camera shake could
cause blurred images.
The higher the sensitivity, the faster the shutter speed becomes even in low
light conditions. However, the image may show more noise (grainy effect).
