The K&F Concept Adapter for Nikon RF (rangefinder) lenses to Z mount is the first enocuntered by me that makes these lenses focus with correct infinity focus. It is very sturdily built and well finished too. The asking price is not very different from other similar mount adapters. I have ordered more of the K&F units.

Agree on all points there, Richard. However, in order to use the gear combinations I wish one has to settle for less than the top notch accessories.

I finally found an adapter for my vintage Nikkor rangefinder lenses on the Z's that really worked as it ought to.

yes. the best combo is always to buy XXX mount to Leica M in my observation.

and then from Leica M to your desired mount :o :o :o

if i only knew this formula i would have saved money long ago, but alas, i bought an Amedeo Sony adapter :(

As per Ric - I use the Yeenon Leica to Nikon Z with helicoid and have M42 to M as well as M42 straight to Z both in K&F concept.

The Yeenon works well and is nicely machined (it looks exactly like the Shoten helicoid). Here on minimum and maximum extension

I bought a cheap FOTOFOX dumb Sony E to Nikon Z adapter for the Voigtlander 15/4.5 III. The adapter is slightly too thin (by about 0.1mm as measured with my digital caliper). By the lens equation, 0.1mm is the extension required for a 15mm lens to focus to 2.265m. Indeed, at f/4.5 infinity focus on my Z6 is achieved just slightly from the 2m mark. Unfortunately, the 15/4.5 Super Wide Heliar does seem to have floating elements, at least the rear group moves at a different rate than the front barrel. This means that I'm likely not getting all that this lens is capable of. Of course I have no way of checking whether the lens itself is within tolerance.

Does anyone know a Sony E to Nikon Z adapter that is dimensionally accurate?

Has anyone found an extension ring for the Nikon Z cameras that is very, very thin?

15mm is the thinnest known to me. Anything thinner has to be a DIY project. I do have the parts, but not the inclination to go ahead and shave a few more mm off.

I have seen 10 and 11mm rings sold on ebay. I'm assuming you need thinner than that.

10-11mm with Z bayonets on either side? I'll have to search for such. I guess they don't relay the signals through the adapter?

EDIT: most interesting, I found some from Meike with contact pass-through.

Earlier Kenko products (for F mount) were rather shoddy. I think I'll order the Meike instead. *Done*

Thanks for the information and the links.    The Meike double-adapter (11mm/18mm)  is very interesting. Especially with the contact pass through.  I wonder how it will work with the FTZ-adapter.

Not all combinations work with the FTZ. One has to try in practice.

I think it's better to put such extension onto native Z lenses.
