ABSTRACT:
A shutter device for a camera with an adjustable aperture comprises a connecting member for connection to a camera lens, the connecting member disposed along an optical axis; an image aperture disposed along an extension of the optical axis; and a reflective shutter and a shutter which are configured to cover the image aperture at least over a pre-settable period of time on a connection side of the image aperture facing the connecting member. The reflective shutter is disposed rotatably via a reflective shutter shaft, and the reflective shutter shaft is disposed perpendicularly to a plane of a reflective surface of the reflective shutter. The shutter is rotatably disposed via a shutter shaft, such that a combined shutter region results from projection in a direction of the optical axis to the image aperture, which is composed of a shutter region of the shutter and a shutter region of the reflective shutter.
