Comments about Nikon Nikon Replacement SB-R200 Wireless Remote Speedlight for the Close-up Speedlight System.:
Bought a third unit to add to the two that come with the R1 kit. I mount two on the ring on the front of the lens and use the third one with the diffuser that comes with the kit. Third strobe with diffuser adds studio-like softness to macro shots of insects and other small subjects in the field. Also supplements relatively low output you get with just two strobes.
