Hah!

As you can see just buying a newer model does not necessarily produce better images.

Low light without flash is when you use the higher ISO settings.

Low ISO's are the best when shooting in bright sun or using the flash ... they have the least noise and the best colour saturation.

In your case, you actually lost a little ground when you "upgraded"

For sure you lost when you went from a 4x to a 3x optical zoom

Too bad you didn't buy the SD1100 IS  at least you would have image stabilization.
