Features an 8-leaf design for more control along with a black reflector dish for shaper shadows. The large doors are also designed to be compatible with the Aputure F10 Fresnel. Note although the F10 Barn Door Set is compatible with the STORM 700x the F10 Fresnel is not – the CF10 Fresnel is specifically designed for the STORM 700x and the smaller STORM 400x. We also stock the CF10 with it’s own Barn Door Set.
