Alongside the D3200, Nikon announced an optional Wi-Fi transmitter for the camera. The WU-1a clips into the USB socket of the D3200 and allows you to broadcast its images to smartphones and tablets running a Nikon app. The unit allows the camera's live view output to be streamed to the smart device and allows images to be shot remotely ( at a distance of up to 49ft, but with no control over the camera's settings) .
Initially an app will be available for Android phones and tablets, with an iOS version expected in fall/autumn 2012. We're told the app will allow either full-size or VGA-resolution images to be transferred from the camera, but we have yet to see how long it would take to grab a 24MP image. We would also like to see how securely the unit attaches to the camera, given that it sticks out of the side, and looks like it might be a little easy to dislodge. It also requires the port cover that reaches all the way up the camera's flank to be left hanging open all of the time that it's in use.
