ABSTRACT:
A small pocket type camera is provided which includes a plurality of picture-taking lenses and a corresponding plurality of viewfinder lenses. The lens system is arranged so that upon changing the picture-taking lens from one system to another the appropriate viewfinder lens will automatically be moved to the viewfinder optical axis whereby the magnification of the subject to be photographed, as seen by the user through the viewfinder lens, will correspond to the magnification of the subject as recorded on the film through the picture taking lens.
