    And it should only be noticeable on very long focus pulls.

    Breathing also becomes a major issue if you plan to integrate any CGI into the footage. Trying to 3D track a camera zoom is hard enough... Trying to duplicate the very small focal length shifts caused by breathing is extremely difficult, if not impossible.

    I find breathing is worst on 2/3 inch video zoom lenses. Cameras with fixed lenses are not true zoom lenses but varifocal lenses. Focus and image size changes during 'zooms' are corrected by the motors in varifocal lenses.
