A rotary photographic shutter includes a base plate, a rotating ring, a plurality of shutter blades pivotally connected to the base plate, and moveable between an open position and a closed position in response to rotation of the ring, and an actuation assembly connected to the base plate, the actuation assembly includes a drive arm operable to selectively rotate the ring. The exemplary rotary photographic shutter also includes a bumper assembly comprising at least one resilient element fixedly disposed with respect to the base plate. The drive arm impinges the resilient element when the plurality of shutter blades is in the open and closed positions, and the drive arm is isolated from contact with the resilient element when the plurality of shutter blades is between the open and closed positions. The exemplary rotary photographic shutter also includes a damper fixedly disposed with respect to the base plate such that at least one shutter blade of the plurality of shutter blades impinges the damper at the open position and is isolated from contact with the damper at the closed position.
