The Nikon WR-T10 Wireless Remote Transmitter is designed to work with the WR-R10 Wireless Remote Controller (transceiver) to wirelessly control the shutter release on Nikon D-SLRs. The WR-T10/WR-R10 units use radio frequencies to communicate; by pairing together a WR-T10 and one or more WR-R10 units. The Nikon WR-T10 Wireless Remote Transmitter enables you to control key camera functions from a distance, even if there are objects between yourself and the camera. Compatible with specific Nikon D-SLRs, these devices allow control of autofocus, video recording, continuous shooting and silent shooting, as well as a feature allocated to the function button. You can use the wireless transceiver and the wireless transmitter together to trigger a single camera, or attach the WR-R10 wireless transceiver to multiple camera bodies and capture the same moment from different perspectives.
