An image-forming system, for example for a camcorder or digital still camera, comprises an object ( 1 ), such as a display, a multi-element magnifying optical path ( 8 ) and focal length varying means for addition, adjustment or removal of one or more elements ( 9 ) in the optical path in order to vary the distance between a viewer's eye and the system, at which distance the magnified object can be viewed.
