发明名称 Camera with self-contained flash device
摘要 A camera includes alternatively operable first and second objective lenses and a self-contained flash device having an irradiating angle substantially coincident with the angle of view of the second objective lens, the second objective lens having a focal length and F-number greater than those of the first objective lens. The camera is equipped with a light diffusing plate adapted to move into and out of the optical light path of the flash device in association with the operable transfer operation between the first and second objective lenses, and the light diffusing plate is so arranged as to be positioned in the irradiating optical path of the flash device when the first objective lens registers with the picture-taking optical path, so that the irradiating angle of the flash device substantially coincides with the angle of view of the first objective lens.
