Nikon’s WR-R11a wireless transceiver and WR-T10 wireless transmitter let you control key camera functions from a distance, even if there are objects between yourself and the camera. Compatible with specific Nikon interchangeable lens cameras, these devices allow control of autofocus, video recording, continuous shooting and silent shooting, as well as of a feature allocated to the function button. Both wireless remote controllers communicate with the camera at radio frequencies, providing an increased range of operation, and enabling communication even when there is no direct line of sight between devices. Using both devices provides an operating range of at least 20 meters. With two controllers, the range increases to 50 meters or more. You can use the WR-R11a transceiver and the WR-T10 transmitter together to trigger a single camera, or attach the WR-R11a transceivers to multiple camera bodies and capture the same moment from different perspectives.
