I am geting Canon S3 IS camera next week, and I've been reading a lot about it. So, the question is: Which IS mode is better: Continous or Shoot only? Continous works all the time, and Shoot only is only when shutter pressed half way. Will camera's IS mechanism sooner wear out (malfunction) if it is on Continous? I want it to work properly as long as possible, don't want to be broken after few months... Tnx.
