My AF-S Nikkor 80-200 f/2.8 D lens will not autofocus on my new D750. However, it does AF on my friend's D810.
The AF switch on the camera has been turned off and on repeatedly.
AF-C and AF-S are set to "release". AE-L/AF-L is set to AE.
It has been suggested on another forum that the DC/DC converter on the lens should be replaced.
