An eye fundus camera includes mainly an illumination optical system, a photography optical system, a photography switch, a controller, and a display. The photography optical system includes a first filter and a second filter. The first filter exhibits a spectral characteristic of intercepting light of wavelengths falling within the first wavelength band and transmitting light of wavelengths falling within a second wavelength band of longer wavelengths than the first wavelength band. The second filter exhibits a spectral characteristic of transmitting light of wavelengths falling within a wavelength band which covers the second wavelength band and includes part of the first wavelength band and which is therefore wider than the second wavelength band including the wavelengths of the light transmitted by the first filter. At least the first filter can be inserted into an optical path and displaced therefrom.
