I have been using all sorts of manual focus lenses on my Nikon Z6 from the early 1950s and on. I have used all sorts of projector lenses (Schneider, ISCO, Leitz), a wide variety of M39, M42 and Exakta mount lenses. Including many Soviet lenses, DDR lenses, Zuiko, Pentacon, Pentax, Sonnar, Pentax 6x7 to name a few. I am having a blast. I started out using the Z to whatever adapters that you can easily find on ebay and Amazon. But then I switched over to helicoids and I like them much better. Mainly because I can use them like a macro bellows and get much closer focusing than what the lenses were made for.
I do also have the Dandelion chips for some of the fixed adapters that go into the FTZ adapter and that is nice, particularly when I use some the the AI chipless mount lenses such as the Zenitar 16mm f/2.8. This give me control of the aperture via the camera controls.
But for the majority of the lenses, I use manual focusing with the helicoid with not camera electronic or otherwise connection. Up until a few days ago, I had not way to update the lens exif data in the raw .NEF files. Now I do. Check out this free piece of software.

It works great and it allow my photo editing software (ON1 Photoraw) to allow me to play with other predefined lenses once I get editing.
As far as lens adapters and helicoid adapters (not the helicoids themselves, but anything you want to stick on the front of it. This is the guy for me.
