Thank you for viewing. This is a listing for a Nikon wireless remote control set. It can be used with many series such as the Z7, Z6, Z5, and D780. By plugging it into the terminal, you can enjoy multi-camera control and long exposures as a wireless release without cables. Please see the HP for detailed usage instructions. www.nikon-image.com/products/accessory/remote/wr-r11b_t10/ I purchased it but changed my equipment without using it, so it's almost new. Please consider purchasing.
