My digital camera healed itself

I found out that my Canon PowerShot SD880IS camera was slightly misbehaving since 2 days ago. Well I zoomed out to the max, the lens would be suddenly off focus. Other than that, the camera was working pretty fine.

To my surprise, yesterday when I used the camera, I suddenly heard a few clicking sound of some motor readjusting, and then found that the camera fixed itself. There's no more out of focus problem since then. Wicked.

I think part ot the reason that the lens or motor in my camera wasn't synchronized well is because I left my camera in my bagpack all the time, and I always treat my bag like I treat myself: slamming everywhere. So from now on I will leave my camera at home, and let the cheesy camera in my mobile phone does the job should I have a need to take pictures on the fly.
