IS on or off?
When shooting in well lit/sunny scene...do you have your IS on or off? Will it make a difference in image quality?
You are as likely to have hand shake in sunny weather as in low light.
Keep IS on whenever hand holding, turn it off when you have your camera on a tripod.

I have been thinking about that for a while actually..
I have learned to use the camera without IS at anything over 1/80s and have no blurry pictures... i think at those speeds the shutter is fast enough that IS is not needed..
Ive tried it a few times to turn off IS (during day) and i havent seen much of a difference in picture quality... Ive seen a little bit of a difference at night though.. its still minimal in my opinion but if u want truly the best out of your shots, it may be worth turning it off...

You'll find that you might need it more at the long ends of the telephoto too. If you're zoomed out to 12X any motion from your hand will be magnified a bit. That's why those pro sports photogs on the sidelines have those ginormous image-stabilized telephotos. They're definitely shooting at faster than 1/80s, but they still need the IS because of the long zoom.

Precisely, the rule of thumb is don't let your shutter speed drop below your focal length if you're hand holding it (without IS).

The advantage of IS is that even at 12x zoom, I find I can get sharp pics at 1/200, or even 1/100 if I am really careful. Turn off the IS, and you will not be able to do it...
