Your best bet will probably be to turn it on, test it in a few different environments with a handful of pictures, and see what the improvement is over it deactivated. From there, you can decide if you'd like to continue using it.
Re: Should I turn on anti-shake camera feature or not?
well as I have tested it images with anti-shake on produces so many noise in low light compared to the anti-shake off .. so if you want decent photos in low light I suggest turning the anti shake feature off.
