Selecting [AUTO] sets the optimal
ISO speed according to the light
level when shooting. Since the ISO speed setting will auto-
matically be raised in dark places, the camera will select a
faster shutter speed and reduce the chances of camera
shake.
Selecting [HI]* sets the sensitivity to a higher value than the
[AUTO] setting. This sets the shutter speed faster, reducing
the potential for camera shake or blurry subjects compared
with the [AUTO] setting.
* Noise in the recorded image may be higher than for the
[AUTO] setting.
When in (Auto) shooting mode, only [AUTO] or [HI] can
be selected.
