Abstract: A digital camera (1) with interchangeable lenses, having provision for removing dust out of said camera (1) through lens mount (6), said camera (1) having a transparent pane (3) positioned in front of shutter (5) in close proximity to said shutter (5) at a distance behind said lens mount (6), sealed around its edges so that said dust cannot settle on said shutter (5) or image sensor (4) positioned behind said shutter (5) inside said camera (1), said dust settling on said transparent pane (3), being easily accessed through said lens mount (6) for removal through said lens mount (6).

Abstract: A device for transporting film (5), in particular unperforated film (5) without slippage, in particular intermittently, powered by at least one electric motor (8), having at least one element such as a needle point (2) mechanically engage film (5) by entering it and transporting film (5) from a start position to a stop position. An element such as a pressure plate (7) may be used in one embodiment to hold the film steady during exposure and a movable element (7) may act on the film to hold it during exposure. At least one mark may be exposed on film (5) to aid in picture registration. At least one roller (31) controls the length of loops of film (5) before and after the aperture. The roller (31) may transport the film (5) by friction, or, in another embodiment the roller (31) may have radially mounted needles (2) which penetrate film (5) to hold film (5) while transporting it.
