Hi thinking of making the move to mirrorless from nikon d850 to z7 11 but my dilemma is my tamron 24 70 2.8 g2 lens have seen on utube a few months ago people having trouble with focus issues the z7 11 with the ftz adapter our should I sell it and get the camera with the kit lens a nikon 24 70 s f/4 i have the tamron tap in control and have updated the firmware so should work but wondering if anyone had this set-up
