Well, Birna, taking a step backwards from the sophistication of these new lenses, I can report that I hope for my promised efforts to embrace the new camera are over, as my adaptor arrived today. It is a NIK- NIK Z K & F Concept adaptor for full frame Nikons, namely Z6 and Z7. Have I assumed correctly that it will do the job on the new Nikon, or do I have it all wrong, and will have to buy another dumb adaptor and have to wait for the full framed version, in order to use it? It looks like one of the adaptors featured in recent posts in this forum.
