Now you can convert any 4x5 view camera into a panoramic roll film camera. This redesigned slide-in roll film holder features the increasingly popular 6 x 12cm (2 1/4 x 4 1/2") format for wide angle vistas and panoramic effects. The unique, slide-in design of the C2N allows it to be used with virtually any 4x5 view, field or technical camera with spring or Graflok back. It slides easily into the camera back like a double sheet film holder - without removing the ground glass frame. The ability to use 120 ( 6 exposures ) or 220 ( 12 exposures ) roll film offers an economic advantage over sheet film as well as numerous handling conveniences, such as easy (and liberal) bracketing and quick film changes in the field. The C2N 6x12 Roll Film Holder combined with a view camera also provides a full range perspective and image control movements with any focal length lens.
