SB-R200 Wireless Speedlight
With it's 3V CR123A battery giving about 290 flashes. This is Nikon's entrylevel flash, that will work with your SB-600, SB-800 or SB-900 in a CLS - Creative Lighting System - setup adding flash in a multiple flash setup. I had the hope of easily creating the R1C1 system myself, but Nikon doesn't make that easy for you. You need the SX-1 adapter, SY-1 ring, SU-800 (and the UR-5 for the 60mm f/2.8) and another SB-R200 to create your macro flash setup.
