PURPOSE:To simply compose the camera, to suffice the accuracy for range finder and to prevent its parallax. CONSTITUTION:Mirrors 18, 19 are moved to a position out of the optical paths of optical systems for range finder and finder at the time of ordinary photographing and a light beam is projected from IRED 11a-11c to an object 16 through a projection lens 12. The object 16 is observed by a photographer through an objective lens 13 and an eyepiece lens 14 and photographed on a film 17 through a photographing lens 15. The mirrors 18, 19 are moved on the optical path at the time of macro-photographing, the photographer observes the object 16 on the optical axis of the photographing lens 15 by means of the eyepiece lens 14 through the mirrors 19, 18 and the projection lens 12. |
