| description | The present invention provides a shutter and a photographing apparatus, and pertains to the field of photographing apparatus technologies. The shutter and the photographing apparatus are intended to solve a problem that a shutter mechanism may be damaged by a large impact force when the shutter mechanism closes an exposure opening. The shutter includes: a shutter base including an exposure opening; a shutter mechanism including a blade assembly and a synchronizer ring for driving the blade assembly, the synchronizer ring being movable between a first position and a second position, and the exposure opening being open when the synchronizer ring is in the first position and closed when the synchronizer ring is in the second position; and a braking member for decelerating the shutter mechanism. In the shutter and the photographing apparatus according to the present invention, the shutter mechanism may be buffered when the blade assembly closes the exposure opening of a camera, so as to prevent the shutter mechanism from being damaged. |
