Nikkor adapter for NEX-6
Beware! I have the Fotodiox, and it has a bad light leak. If you are outdoors, and the sun is at the right angle to hit the adapter right at the "lever" you push to remove the lens, you'll get a bad light leak.
If you have one of these, you can see the effect by shining a flashlight on that part while looking at the screen.
I now put a piece gaffer's tape over that section of the adapter when using it. A big rubber band or elastic wrist band would work, also.
