CONSTITUTION: The visual field frame 5 is guided by guide parts 1a, 1b, 2a and 2b provided on a finder block 1 and a cover 2 and slided in an oblique direction. The macro display plate 6 is slided left and right by being guided by a block 1e part and a cover 2d part. Then, a torsion coil spring 7 for the visual field frame which switches the positions of the frame 5 and the plate 6 and a lever for a visual field frame 8 which controls the spring 7 are provided. That means, the mechanism which moves not only the frame 5 but also the plate 6 at the normal/macro switching time of the photographing lens is provided. Thus, the macro display is clearly executed within the visual field of a finder even though it has a small space.
