Pois é, olha o caso da D7000. Sei que não é FX e foge to topico mas é bom saber.
Mount Nikon é sempre uma caixa de surpresas. Na Pentax TODAS funcionam, até as M42 com adaptador.
Mesmo da D700 tem muitas incompatibilidades.

https://www.nikonimgsupport.com/ni/NI_article?articleNo=000002313&lang=en_USCompatible Non-CPU Lenses
If lens data is specified using the Non-CPU lens data option in the shooting menu, many of the features available with CPU lenses can also be used with non-CPU lenses. If lens data is not specified color matrix metering can not be used, and center-weighted metering is used when matrix metering is selected.
Non-CPU lenses can only be used in exposure modes A and M, when aperture must be set using the lens aperture ring. If the maximum aperture has not been specified using Non-CPU lens data, the camera aperture display will show the number of stops from maximum aperture(0, 1, 2, etc.); the actual aperture value must be read off the lens aperture ring. Aperture-priority auto will be selected automatically in exposure modes P and S. The exposure-mode indicator in the control panel will blink, and A will be displayed in the viewfinder.
