The Nikon R1C1 Wireless Close-Up Speedlight System (a.k.a. Macro Kit A) is a macro flash solution for i-TTL capable cameras that do not feature a built-in flash (e.g. D2X, D2H/D2Hs, F6). The kit is fully compatible with the Nikon Creative Lighting System and Advanced Wireless Lighting system when used with compatible cameras and/or flashes.
