The WR-R11b is a Wireless Remote Controller that uses radio frequencies to wirelessly control the shutter release on Nikon cameras or radio-controlled flash units such as the SB-5000 Speedlight. The WR-R11b fits cameras with an accessory port. The WR-R11b can be triggered by a WR-T10 Wireless Remote Controller (transmitter), a WR-1 Wireless Remote Controller; it can also be used on a designated master camera to trigger up to 64 transceiver units. Three radio frequency channels are available for use (5, 10, and 15) to prevent interference when multiple pairings or photographers are shooting in one location. Photographers can use the WR-T10 or WR-1 to simultaneously release the shutter on multiple cameras that have a WR-R1b unit attached and have been paired with the WR-T10/WR-1.

• Operate Cameras or Flashes Remotely: Provides flexibility to control multiple cameras or flashes to ultimate control and creativity
• Connectivity: The WR-R11b connects to the accessory port on select Nikon cameras
• Power: The WR-R11b is powered by the battery of the camera
• Channels: Three radio frequency channels are available for use to prevent interference when multiple pairings or photographers are shooting in one location
• Range: Range (line of sight) from the WR-T10 to WR-R11b is 66 feet (20 meters). Range (line of sight) from WR-R11b (acting as a master unit) to WR-R10 or WR-11a/b units is 164 feet (50 meters). Communication distance between the WR-R11b on the camera and the Speedlight is approx. 98 ft. (30 meters)
• Speedlight Control: When controlling Speedlights, the camera used must be able to support radio AWL (Advanced Wireless Lighting). Up to 18 Speedlights can be paired to the WR-R11b on the camera. Communication distance between the WR-R11b on the camera and the Speedlight is approx. 98 ft. (30 meters).
