The WR-R11a wireless remote lets you wirelessly control your camera’s shutter release or synchronise the shutter release of multiple cameras linked to the master camera. Compatible with specific Nikon cameras, this remote transceiver can also be used to control external flashes—such as the SB-5000 Speedlight—in advanced wireless lighting setups. The WR-R11a is also compatible with the WR-1 remote, a professional-grade controller with long-range capabilities.
