The Aputure CF12 Barndoor for CF12 Fresnel is an 8-leaf lighting accessory designed to shape and/or cut light with just a couple of manual movements. This set of barndoors attaches to the front of the STORM 1200x or STORM 1000c using the Barndoor Adapter, or with the fresnel included with the CF12 Fresnel and Barndoors. For further lighting output control, there is an available holder for a 13-inch metal scrim.
