I believe the OP meant tethered shooting like what we do with Nikon and Camera Control Pro. Don't worry cartouche, I can't do it also with my D800, until someone makes the software available in RT.
<snip>Otherwise I think to do that you would need a direct USB connection to the camera and for an app to facilitate the communication as you said.
Exactly... or WiFi.
Will have to get a SD card adaptor/reader and use the USB port
