What are the focus and depth of field considerations in HDTV?
Because of the high resolution of HD, focus is more critical than with regular video. When the cameraman is using the viewfinder as the primary means of judging focus, its crucial that he have proper dioptor adjustment for his vision. Whenever possible, its desirable to have another crewperson (engineer or video tech) helping to watch in a monitor for focus, exposure and other parameters. Alternatively, a film-style assistant cameraman can tape-measure focus distances and control focus from the side of the lens as would be done with a film camera.
