ABSTRACT:
A system for close-up and copy photography is so designed that a zoom lens whose total barrel length remains unchanged during zooming operation is attached to a camera as the master lens with an adapter being attached to the zoom lens and with a fixed focus lens being attached to the adapter on the side opposite the side to which the zoom lens is attached. The fixed focus lens is arranged in a position reversed from the position in which it would normally be used, that is, with its object side facing the zoom lens and with its image side facing toward an object to be photographed. The adapter may have a filter mount mechanism and a securing stand attached to the adapter for holding an object to be photographed is structured to permit illumination of the object.
