NEX 6 with Novoflex getting light leak

Actually, many adapters can potentially have light leak, just not very noticeable under normal circumstances.

I am using a Fotodiox NEX-PK adapter, and I have not seen any light leak on any of the photos I took. But if I go into a dark room, look into the lens front element and shine a very bright LED flashlight right at the adapter release button, I can see small amount of light leak into the camera. I suppose it is very small amount that it is not significant in the photos that I took.
