The electronics part of the adapter works as advertised.
All focus aids of my Nikon zf are available (after a firmware update of the adapter).
But the adapter makes reliable zone focusing impossible due to the wrong thickness of the adapter. All my lenses reach infinity focus way before the infinity stop of the lens (between 5 and 8 meters).
This is an amazing adapter for all Z camera users who are interested in some of the best manual camera lenses available on the market.
My Leica lens works flawlessly with my new Nikon Zf camera thanks to this adapter from TTArtisan and I'm able to capture EXIF data. Well built, solid, no issues adapting the lens to the camera, I would highly recommend.
Great adapter, with a few caveats:
My six M lenses do not have 6bit code. The M-Z ring gets a false reading on several of them. The workaround is to set the focal length and press reset before mounting the lens.
All lenses without 6bit codes appear as maximum aperture f/0.95. This does help somewhat in identifying that the M-Z adapter was used, but limits the available recorded setting to f/5.6. In this case I just regard that as f/5.6 or greater. (6bit lenses set the aperture range properly.)
I also have several lenses that don't have focal length settings available on the M-Z, notably 20mm and 40m. Testing with the closest available setting (28 for 20, 35 for 40) showed a bit of degradation in stabilization, but not too bad. In low light shooting I can revert to a manual ring and use in-camera lens profiles.
Overall the M-Z 6bit adapter ring has greatly improved shooting with M lenses on my Z7. I prefer the combination to my vintage M6.
