The short register distance of the Z system simply begs for experimental setups. I have tinkered a lot over the last year with surreal combinations, and these efforts were again boosted by the arrival of my Z50. Not because the Z50 is the "best" of the range, it' because it's the smallest. Thus some combinations simply work better there -- for me.
The old Ultra-Micro-Nikkor 55mm f/2 really likes being put on the Z50. With a long helicoid it can focus from far away (but not infinity, unless the helicoid compresses narrowly enough) to approx. life-size 1:1. The lens is seriously sharp. Period.
At f/2 up close, the manifested depth of field is wafer thin. Hand-held, no stacking.
A rose by any other name ...
