As I commented in another thread; The two 60mm Micro-Nikkor lenses are very different optically; The old one AF and AF-D works by extension and a CRC group the new AF-S is an IF lens, no extension.
Same goes for comparison to the 50mm Micro Nikkor f/2.8 extension and CRC- We have a long thread on these in Lenses
My 60mm AFS is definetly not as good/preditactable as the old 50mm ones on DSLR
focus shift,,, maybe since the 60mm seems to behave quite good on the Z7
The AFS 60mm is in all regards except minimum focus distance surpassed by the Z 50mm f/1.8 S it even has no focus breathing!
