Abstract
A mirror device for a camera. The mirror device includes a main mirror that directs luminous flux entering the photographic optical path of the camera to a position outside of the photographic optical path. A sub-mirror directs luminous flux passing through a half-mirror forming part of the main mirror to a rangefinding optical unit. The main mirror and the sub-mirror are retractable to outside the photographic optical path. A sub-mirror holder holds the sub-mirror, and is supported by a body of the mirror device so as to be retractable.
