What's the option if one wants Nikon's green box focus confirmation? Stacking Megadap ETZ21 Pro+ and TTArtisan M-E 6-Bit? I'm worried that will mess with the tolerances and degrade performance.
Fred Miranda does lens reviews stacking Megadap ETZ21 Pro+ and Voigtlander VM-E II close focus adapter on his Zf without issue. (you can substitute any decent M-E adapter) However, there are a couple of EXIF issues with the setup:
1. Lens model always written as "Megadap ETZ21 Pro Plus"
2. If you use Megadap's recommended image stabilization settings here:

Thanks. One more question about the Shoten - when you focus a lens to the infinity stop, is that actually infinity in the image?
I haven't rigorously tested this with multiple lenses (nor do I know how the ones I have would operate on an M camera) but from my limited testing the Shoten adapter seemed like it got it a lot closer than many cheaper adapters do. The Voigtlander M to Z seems even better though (but no contacts).

the focal length may be incorrect, since the values aren't precise.
This is correct but not a big deal in my opinion. You can adjust the aperture used, which matters more for EXIF, and you can always change the lens name after the fact with tools like LensTagger.
As for the image stabilization not being precise, I don't see much of a difference. For example: 180° = 30mm. Do you think that would make any real difference for a 28mm lens? I'd say I don't see any problems with this setup.
I see the Shoten setup as much more cumbersome, since you'd actually have to take a picture just to set up the lens. With the Megadap ETZ21 Pro Plus, you don't. Just add this setting (for the angle) to your favorites, and it's very easy to switch lenses and set the correct image stabilization setting.
The easiest by far is the TTArtisan 6-bit, since the adapter automatically sets image stabilization for 6-bit lenses (and correct EXIF), or has an easy Focal Length dial on the adapter itself for non-coded lenses. Unfortunately, this one was discontinued. I have one and love it because it's the easiest to set up the lens, and it's very light, but it doesn't focus as close as my stacked Megadap ETZ21 Pro+ and Voigtlander VM-E II close focus adapter combination.
If you shoot with long E-mount AF lenses adapted through the Megadap ETZ adapter, it completely bypasses the "manual-lens angle hack" mentioned above. That hack for setting focal length only applies to manual lenses without electronic contacts.
So if you're using a long non-chipped MF lens on the adapter, you're stuck relying on that angle setting, but these lenses are almost always manual focus to begin with, so how often are you really shooting a very long manual focus lens? I'd say the practical limit for most people is around 135mm, and the 105+ angle setting works well enough at that range.
For instance, my longest Sony E-mount lens is the Batis 135mm f/2.8 APO, which is chipped, so the adapter reads its actual focal length directly rather than going through the angle hack. And in this lens's case, the adapter uses its own OSS, which tends to be more effective than IBIS at longer focal lengths anyway.
The Shoten adapter is M-to-Z, so it has nothing to do with E-mount lenses. What I do personally, since I want to adapt both E-mount and M-mount lenses to my Zf, is stack the Megadap ETZ adapter with a separate M-to-E adapter, ideally one with helicoid focusing.
That gives me two setups: I run the Megadap bare for AF E-mount lenses, where it reads focal length directly from the lens. And I add the M-to-E adapter on top for my M-mount lenses. It's only in this second case, with M-mount glass, that I'm actually using the angle hack in the menu to set focal length for IBIS.

Think you misunderstood my intent, but that's probably on me. Posted purely for informational purposes. I never look at or edit EXIF - it was only out of curiosity I know how Megadap writes metadata. But on a lot of the threads I see on the forums, it's a **huge** deal for some people. (IIRC I saw a comment on one thread where someone complained a posted image was useless because it lacked EXIF. 🤣🤣🤣🤣

Wholeheartedly agree. Sold the Shoten adapter I bought from you and am currently running the same setup as you, except with the VM-E close focus I.

Never felt the need to try the TTArtisan because I'm happy with the stacked setup.

Yes, the "Focus Ring Rotation Range" trick was a really smart move on Megadap's part. Once you've used it, you don't want to deal with the alternative. With the Megadap, I just press a custom button, dial in the angle that corresponds to my lens, and the IBIS is set. No taking a test picture, turning the camera off, turning it back on, and so on every time you swap lenses using the Shoten.
That convenience is what keeps me on my stack setup (Megadap ETZ plus a dumb M-to-E close-focus adapter). My stack weighs 115g, which comes out to about the same price as the Shoten M-to-Z with close-up ability.
I have some E-mount autofocus lenses as well, so when I want AF, I just remove the M-to-E adapter and use the ETZ bare. As for EXIF, it's nice too, since I can set the aperture, and in post, I can change the lens name and so on.
Looks like the Sony 6bit Adapter is gone, now, too..
I didn't need the 6bit feature since my only Leicas are R lenses (although I did consider buying R-M adapters with 6-bit squares to paint myself), but being able to easily adjust focal length when switching lenses was pretty awesome..
I really hope mine keeps working. (I also have the Neewer but the hassle of adjusting the focal length in file pushed me towards the ttartisan one)
Still think Nikon should finally get their knickers untwisted and friggin' enable focus confirmation with a firmware update...
The silly arguments along the lines of "camera needs to know focus ring position in order to function properly" simply don't work... we've all used different focal lengths of different lenses with great success with the green focus confirmation.
