Differences between the Nikon D3100 and D3200
Unlike the D3100, the D3200 is Wi-Fi enabled, provided you purchase the incredibly small WU-1A transmitter (£54.99) that’s offered as an optional extra.
This small unit connects to the D3200 via the mini-USB socket on the side of the camera and allows you to transmit images to a host of devices. Images can be shared directly with Facebook, back-up images to a computer or sent to an Android smartphone or tablet via a downloadable app. As long as your no further away than 49ft, you can also stream the Live View feed from the D3200 to your Android device and be able to shoot remotely as well.
