PURPOSE:To meter reflected light on a film surface by use of a single photodetecting element by providing the 1st optical system which forms a photometric optical path for display that guides external light to a photodetecting element for photometry and the 2nd optical system which forms a photometric optical path for photographing that guides the reflected light from the film surface in exposure to the photodetecting element for photometry. CONSTITUTION:This camera is provided with a photographic lens 1, shutter 2, film 3, external light lens 4 which collects light from outside the optical path of the photographic lens 1, optical fiber 5 for guiding the light, mirror 6, the photodetecting element 7, film surface lens 8 which collects the reflected light from the film surface, and an optical fiber 9 which guides the light to the mirror 6 that makes the light incident to the photodetecting element 7. When the shutter 2 is closed, the external light is made incident to the photodetecting element 7 through the external light lens 4, optical fiber 5, and mirror 6, and when the shutter 2 is open, the reflected light from the film surface 3 is made incident to the photodetecting element 7 through the film surface lens 8, optical fiber 9, and mirror 6. |
