PROBLEM TO BE SOLVED: To provide a camera for suppressing the measurement error between an exposure control photometric element and a strobe light adjusting photodetector and accurately controlling the exposure without making the camera large in size. SOLUTION: The exposure control photometric element 22 and the strobe light adjusting photodetector 23 are concentrically arranged around a photographic lens 11 and they are assembled integrally with a lens barrel part. Measuring light is made incident on the photometric element 22 and the photodetector 23 at the same angle to the optical axis of the photographic lens 11, then, one measured value becomes equal to the other. In front of the photometric element 22 and the photodetector 23, a belt like loop filter plate 25 is arranged so as to be freely rotated around the photographic lens 11, and L filters 26a and 26b, M filters 27a and 27b and D filters 28a and 28b having different light transmissivity are installed on the filter plate 25 side by side in the circular arc direction of the filter plate 25, and in the case of rotating the filter plate 25, the filters having the same light transmissivity are confronted with the photometric element 22 and the photoreceiving element 33. |
