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 WR-R11a Remote Controller
Designed for use with Nikon cameras featuring a 10-pin connector, the WR-R11a Remote Controller can be used to wirelessly trigger the camera's shutter when paired with the separate WR-T10 or WR-1 Wireless Remote Controller. It can also be used to trigger select radio-enabled flash units or as a master to trigger up to 64 transceiver units. Additionally, suiting its use in busier environments, three selectable radio frequencies are available for reliable use.
Nikon WR-T10 Wireless Remote Controller Transmitter
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.
