Add WiFi To Your Nikon D4 For $30
If you are one of the lucky few who now own a Nikon D4 there is a good chance that you wondered why Nikon did not include WiFi on its flagship.
It does include an Ethernet port allowing for wired control and live view, but no WiFi.
You could of course, add WiFi with the WT-5A, but that would mean saying goodbye to another $900. This is kinda weird of Nikon side, especially when the lower-end, soon to be announced, D3200 is rumored to have WiFi capabilities.
Nikon Rumors shares an interesting, and more affordable option to add WiFi capabilities to the D4 (or any camera with an Ethernet port for that matter) - using a VAP11G portable WiFi bridge.
