Image Stabilisation problems

[swamp]

I'm planning to buy a Canon S2 IS because I like the image stabilization feature and all else about it that I've read.
Please let me know if you have had problems with the image stabilization in S2 or another Canon camera. Also, how will I know if there is a problem? Will an error message appear, or will I just start seeing blurred pictures?

the S2 and S3 have same IS tech. I have the S3. IS is awesome almost perfect. I zoom in full optical, very stable. and i have a shaky arm/hand. I actually took some moon shots last night at full zoom (full digital) with the IS on, its very good for a handheld shot id say.

You almost have to have it when you are zoomed in that far. The only way you could get good shots with that much zoom is with a tripod and using a timmer. It works good though, it can lag the display if you dont set it to "Shoot only" that way it kicks on the IS just before the picture is snapped only.

i think the is works really well
