Nikon WR-R11a WR-T10 Remote Controller Set
An efficient bundle for wireless camera and flash triggering,
the WR-R11a/WR-T10 Remote Controller Set includes both the WR-T10 Wireless Remote Controller
and the WR-R11a Remote Controller for cameras featuring a 10-pin connector.
Nikon's WR-T10 Wireless Remote Controller Transmitter is a remote control transmitter designed to work with the Nikon WR-R10 Wireless Remote Controller transceiver (available separately): together, they control the shutter release on Nikon DSLR cameras wirelessly. The WR-T10/WR-R10 units use radio frequencies to communicate--you can trigger any number of Nikon DSLR cameras equipped with WR-R10 units, using one WR-T10 controller.
The WR-T10 can control the shutter on an unlimited number of cameras with a paired WR-R10 unit attached.
Three radio frequency channels are available for use, to prevent interference when multiple pairings or photographers are shooting in one location.
Useful for triggering the shutter remotely when using slower shutter speeds, to prevent camera movement.
Range from the WR-T10 to WR-R10s is 66 feet (20 meters).
