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.
The kit's main components consist of the SX-1 Attachment Ring that attaches to the lens filter treads via an adapter ring (included), two SB-R200 wireless macro flash heads, and the SU-800 Commander Unit. The SX1 accommodates up to eight SB-R200 Speedlights off camera, and up to four on camera.
This solution enables excellent close-up lighting control with exceptional flexibility and innovative options. When using the SU-800 with cameras that are not compatible with i-TTL flash control, only close-up flash operation is possible using the optional SC-30 TTL Cord.
Flexible Control
The built-in Speedlights of the D200, D70s or D70 serve as the system's Master controller. Or, for non i-TTL cameras, the SC30 sync cord can be used for off-camera control.
The SX-1 Attachment Ring can accept up to eight SB-R200s and can be attached to a tripod for remote lighting.
