The stabilizer function is used for less blur
picture caused by hand shake under a dark
environment, the camera would increase the
ISO level under the mode to have a higher
shutter speed.
This function may not help to take a clear
picture about a fast moving target, a car
passing by with a speed etc.
This function may not help if you stay on
a fast shaking car, boat etc. It is only for a
normal shoot on a ground by hand.
Increasing the ISO level may cause heavier
noise on the photo.
Use tripod to get a clear picture on ground
is always preferred.
