Abstract
A lens-fitted photo film unit is provided with a movable stop plate formed with small and middle stop apertures. The small stop aperture has a smaller diameter, and the middle stop aperture is larger than the small stop aperture. A fixed large stop aperture, which is larger than the middle stop aperture, is disposed behind the movable stop plate. The movable stop plate is moved to position the small stop aperture at a photographic optical axis when subject brightness is a predetermined reference value or more. Similarly, the middle stop aperture is positioned at the optical axis when the subject brightness is less than the reference value and a flash switch is turned off. Further, the fixed large stop aperture is set to the optical axis when the subject brightness is less than the reference value and the flash switch is turned on.
