I should have asked 'is the AIS not suitable?'
Of course you did not say that it was not, but it fits the description and I wonder what makes you look for an alternative.
The Zeiss lenses of course draw very differently from the Nikon lenses, so I can understand that you may want both.
But now not anymore.
I know that the 85mm ZF.2 is still being sold new. While I suspect that you got a lemon, I also think that the lens (even one that is within spec) does not meet today's demands for high sharpness into the corners. I think that is why the Milvus 85mm is completely re-designed and now much heavier and more complex.
Some other lenses in the Milvus line have the same optics as their ZF.2 counterpart, or only minor changes.
