Summary: This is a great camera except for the lens. I previously owned Powershot S110 and S400's, both of which took perfect images; the SD1000 seems to have a lower visual quality. Even as low as 1600x1200, in good light, you get severe blurring and smudging in the corners - you can't see it in the viewfinder, but on a monitor, it's quite noticeable. I sent it back to Canon and they replaced the lens, but it didn't help.
Pros: Amazing battery life, Focuses FAST, Takes great movies, Tiny, Turns on fast
