Nikon 4255 WR-R11a/WR-T10 Remote Controller Set

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.
