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 of a fast moving target, such as
a car passing by, etc.
This function may not help to stabilize
photos if you are in a moving vehicle (car,
boat, etc.). It is best used when taking
normal shots.
Increasing the ISO level may cause heavier
noise on the photo.
Use of a tripod is always best to get the
clearest picture.
