A question about the Canon S2-IS and other similar models. When you go to movie clip mode, do they allow 1) use of the telephoto during the filming? 2) doe the camera do either auto exposure or timing adjustment during the filming?

I have a Canon PowerShot S30 and you are stuck with the lens and exposure the camera picks up on the first frame of a movie clip.

Not a minutes trouble in about 5 years. 3.2 mega pixels and great pictures. I do not need a camera to take pictures of such detail that I could make poster sized print. Would I like one, yes.
