Hello, It is my understanding Nikon will introduce a full frame 'mirrorless' camera in the spring of 2019. It is also my understanding, similar to the Sony A7 and A9 series, the old lens line will not work with the new camera without an adapter. It is also my understanding the adapter interface to the camera will not be as robust as a direct attached lens.

With that said, I assume Nikon will introduce a completely new line of lens shortly after the announcement of the new camera making the old line of lenses obsolete.

Does this sound correct? Terry Johnson

PS: I believe Canon is also introducing a mirrorless camera?
