Abstract
A compact camera contains a plurality of objective lenses which are selectively alternatively advanced by external manipulation into registry with the camera photographing optical axis to vary the image magnification. A view finder optical system is provided which includes a lens member which is movable into and out of registry with the view finder optical system to vary the viewer field to correspond to the field of the operative objective lens. A lens storage space is provided between the laterally spaced view finder and photographing optical axis, one of the objective lenses when retracted occupies the storage space and when this lens is advanced to the photographic optical axis it may be replaced in the storage space by the retracted view finder lens member.
