ABSTRACT:
An eye fundus camera system is provided with a photographic optical system and associated optical axis, an illuminating optical system and associated optical axis and a mark projection system and associated optical axis. The illuminating system is separate from the mark projection system so that operation of the mark projection system during focusing of the photographic optical system will not adversely affect the illumination of an eye fundus.
