Hmmm...I know my camera has different modes that change how/when it focuses (and I tend to use more manual modes, anyhow, because my background is in photography and I loathe full-auto...I'm a control freak), so that I can avoid having that focus motor constantly twitching. Is there a way on the camera you have to do this? I'm guessing the cheapy ones don't offer that much adjustability, unfortunately.
