I am just wondering if there are any very narrow (thin) extension tubes for the Nikon Z camera?

Since there are no good macro lenses I know of for the Z7 II Nikon, I am trying to cobble together an autofocus Z lens with a very narrow extension. The best I have so far is the 85mm Z f/1.8 and an 11mm extension. Any ideas?

BORG makes a thin Z to M48.9 P0.75 adapter whose part number is 5032:

Borg also makes an M49.8 to M42 adapter ring to make the Z-mount compatible with the more common M42 P1.0 thread.

In the second image, the two rings on the bottom right which are BORG Sony E and m4/3 mounts which look similar to the Z-mount mentioned above.

The ring on the top right is the M49.8 to M42 adapter.

How thin are these rings, please?

I understood Michael to enquire about extension with pass-through contacts. Otherwise there will  be no AF :(

I think 11mm is about the narrowest you can get these days.

Oops...I failed to read the second paragraph.   :-[   I'm afraid its thickness is not indicated in their website.

There is a 10mm one I believe from Fotodiox that is part of a 2-adapter set, but the set goes for over $200....

Kenko/Tokina makes a set of Z-mount 10mm and 16mm extension rings with contacts.  But the set also costs around 200 USD:

I would like to, of course, see one about 8mm which would preserve the quality of the lenses used with it a bit more.
