Here's a way to get perspective control on the Sony NEX. We can use a Micro Four Thirds to Sony NEX E-mount Lens Adapter to connect the Fotodiox Shift Adapter shown below. The shift adapter comes in many different mounts which accept Minolta SR, Leica R, Nikon, or Canon.

Another option would be to use a Nikon to a Sony NEX E-mount lens adapter and a Nikon PC-E lens. Canon also makes a tilt shift lens and you can use a Canon to Sony NEX E-mount lens adapter.
