WR-R10/WR-T10/WR-A10 Wireless Remote Adapter Set
The WR-T10/WR-R10 Wireless Remote Controller units use 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
Features
Simultaneously release the shutter on multiple Nikon D-SLR cameras that have a WR-R10 unit attached and have been paired with the WR-T10
Trigger the shutter remotely when using slower shutter speeds, to prevent camera movement
Three radio frequency channels are available for use, to prevent interference when multiple pairings or photographers are shooting in one location
Range from WR-R10 (used with the WR-A10 WR adapter on select D-SLRs, and acting as a master unit) to WR-R10s is up to 164 feet (50 meters)
Compatible with Nikon D300S, DX3, D4, and D800
