    The manual states that before shooting movies, press the shutter release half way down and the camera will auto focus depending on which mode is set. So once you start shooting, and your subject distance changes, for example a motor race where the cars come towards you, gets close and then goes away again, do you have to keep pressing the shutter release half way to keep the subject in focus?

    You can't focus whilst recording, so yes you have to focus first and then start recording. Manually pre-focus would be one option.

    Thanks Justin, that's what I had deduced so one has to be careful not to go outside the focus limits (DOF) as set by the aperture.

    You can always focus manually......best done in conjunction with using an external monitor,which makes it easier to see what you're doing.

    True Roger but I'm not thinking of making full length epics, just a few shots of, for example, the flood down the Gorge this last week.

    Cheers
