The Jupiter 12 2.8/35mm works fine on the Nikon Z6. You just have to be careful not to hit the unprotected rear lens when mounting/unmouting it but this is a lens problem not a camera one.

I am using a Nikon Z6 with a Leica M to Nikon Z adapter and Leica M lenses or 39mm lenses+Leica M adapter. This way I have a full frame sensor and even funny lenses like a 12mm Voigtländer first generation work reasonably well.
