Nikon WR-10 Wireless Remote Controller Set
The WR-10 Wireless Remote Controller set uses radio frequencies to communicate, by pairing together a WR-T10 and one or more WR-R10 units. The WR-A10 WR Adapter is designed to work with the WR-R10 Wireless Remote Controller (transceiver), allowing it to be connected to select Nikon D-SLRs with a 10-pin connector, to wirelessly control the shutter release. D-SLRs without a 10-pin connector do not need the adapter.
