In a fundus camera equipped with an optical system for observing and photographing the eye to be examined, and an illumination optical system for illuminating the eye to be examined, each operation section is connected to the optical path of each of the optical system and the illumination optical system. A separate filter supported by a movable means is disposed so as to be removable together with the movable means, and further includes separate switches that operate in conjunction with the movement of each movable means into and out of each optical path. A light emitting means that blinks when a switch is operated is provided near the operation section, and when the respective filters enter or exit the respective optical paths together, the light emitting means continues to light up, A filter warning device for a fundus camera, characterized in that the light emitting means is configured to blink repeatedly when one of the light emitting means enters the optical path and the other exits the optical path, or vice versa.
