I was using a friend's S3 IS and have a few questions:
1. How do you turn on the IS feature?
2. How do you activate auto-focus?
3. Pressing the MF button displays the square on screen that allows me to focus on that item. It seems that I got it to focus, though I was able to continue to focus on it more and more until it reached the infinity icon. By doing this, does it automatically blur out other parts of the image? Is there a certain point it should only be focussed to?
