Nikon has two apps that can turn your smart device into a remote release. These apps are Nikon Wireless Mobile Utility (WMU) and the newer, more sophisticated, Snapbridge. The apps are free downloads from the app stores. There are a number of configuration setups, depending on your camera.
If you have a D3200, D3300, D5200, D7100 or Df you will need to get a WU-1a Wi-Fi adaptor to use this feature. If you have a D600 or D610, you would need a WU-1b Wi-Fi adaptor. For D5300, D5500, D7200 and D750 you can connect directly to WMU using the camera’s built-in Wi-Fi. Snapbridge is compatible with D3400, D3500, D5600, D7500, D500, D780, D850, D6 and all Z-series cameras. The full compatibility lists can be found on the Nikon website: https://bit.ly/snapbridgecomp…
