The Nikon closeup R1C1 kit gives you all the lighting you need for close-up shots, including the SU-800 Wireless commander, two SB-R200 wireless flash units and the SX-1 attachment ring. The kit also includes a set of adapter rings, diffuser, and a bunch of other handy accessories all in a dedicated case. This completely wireless system means you don’t get any unexpected shadows caused by an errant cable and (thanks to Nikon’s Creative lighting system) enables wireless remote shotting group flash control.
