Focus distance indicator

On my Z50 when using manual focus with the 16-50 Z lens, the Focus distance indicator feature is activated. When using manual focus with my 18-140 DX with the FTZ and the lens switched to M, manual focus works fine, including focus peaking, but the Focus distance indicator feature is not activated. Would this be normal?

That's how it works on my Z5. I read somewhere that the focus distance indicator only works on Z mount lenses.

dachshund,

I have no focus indicator when using my 18/300 or my 200/500 F mount lens. Like Clovishound I thought I read it in the manual but could not find it.
