Ah yes, of course. I'm too used to thinking of adapting lenses being down to just the registration distance.I don't think so. Flange distance is one thing. The other is diameter. Nikon Z has 16mm flange distance and 55mm in diameter. Sony E has 18mm distance and 46.1mm in diameter. Leica L has 20mm distance 51.6mm in diameter.
So for E to Z, you have 2mm in distance and almost 9mm in diameter difference for the adapter.
For L to E you would gain 2mm distance but you would have only 5.4 mm in diameter difference. The thing that E mount in the narrower one makes it even more problematic.
