An eye fundus camera including a photographic system for photographing the fundus of an eye and forming an imaging optical path having an illuminating system for illuminating the eye fundus and forming an illuminating light path, a barrier filter releasably seated in the imaging optical path, and an exciter releasably seated in the illuminating optical path. The apparatus also includes a diaphragm arranged in the illuminating optical path for changing the illuminated field on the eye fundus, an optical device in the imaging optical path for changing the magnification of the photographic system, or an apertured plate in the same path to change the photographic field, and a drive connection device responsive to insertion of the barrier filter and exciter into the path for enlarging the diaphragm and for reducing the magnification of the photographic system, or increasing the size of the opening in the apertured plate.
