I decided to go ahead and order the z6 kit, and I’m loving it so far. My only issue is that my 70-300vr is not working at all with the z6. When I mount it with the FTZ and turn on the z6, the lens makes a horrible almost grinding noise. I have tried turning the lens vr and autofocus switches off, none of this fixes it. While the noise is happening the vr and autofocus do not appear to be doing anything. After a few seconds, the noise stops and I’m left with the error message “Error. Press shutter-release button to reset”. When I press the shutter button, it starts the noise again. And the cycle continues. If shooting in auto or one of the user modes, I get the message saying no lens is attached or the attached lens is a non cpu lens.... this is the older af-s Nikkor 70-300mm 1:4.5-5.6G but is still afs, so I thought it should work fine. The lens and all functions work fine on my D700, D80, and my sisters D7100. Anyone else have a similar issue? Any ideas on a fix, or do I need to go shopping for a replacement 70-300?
