摘要：
A photovideo camera takes visual images formed on negative films and/or positive films to obtain video signals corresponding to the visual images. The camera unit of the photovideo camera can be focused after determining a desired angle of view by zooming, without changing the desired angle of view. In focusing the lens unit, only the master lens of the focusing lens system of the lens unit is moved.
