Nikon registered two new unannounced wireless remote controllers N1839 and N2012 with the Taiwan NCC. Both devices support 2.425GHz/2.450GHz/2.475GHz and are most likely the successor to the Nikon WR-T10 and Nikon WR-R10 that have been out of stock for a while (same with the Nikon WR-R10/WR-T10/WR-A10 wireless remote adapter set): Via Nokishita No related posts.
