It's a bit ironic that I don't actually have any Nikon lenses at the moment, aside from the Voigtländer 35mm f/1.4 Nokton Z-mount that I will be reviewing. Here are some of my lenses adapted to the Nikon Zf.
Basically, I'm using the Megadap first to retain full electronic communication. With M-mount lenses, I add a Voigtlander close-up adapter for an extra 5mm of extension when needed. For Voigtlander MF and AF E-mount lenses, they mount directly onto the Megadap.
That looks like a native setup with the silver adapter and safari lenses. Can you mount Steel Rim on it to see what it looks like. I just bought the A7R5 and 100-400 just for Yellowstone. Wish I read this thread, and I would just get the ZF to adapt all my M mount lenses and still get a Z mount tele.

In the 'Non-CPU Lens Data" menu, you can enter details like focal length and lens name. When you select one of those saved lenses, does the camera actually use the entered focal length for IBIS?
What I'm really trying to understand is whether the focal length you input there is what IBIS relies on. That’s the main concern when adapting lenses, and the reason you still have to enter focal length even when using electronic adapters.
Yes to your question, non-cpu data drives IBIS...unless you have a chipped adapter on which you do the same. Then the reported focal length from the adapter is gospel and used for IBIS.

In the video, the steps for "trap" focus are:
Set Focus Mode to AF-S
Set AF-S Priority Selection to Focus
Set AF Activation to On
I followed these settings, but when I fully press the shutter as described, the camera still takes the shot right away instead of waiting for focus confirmation. I’m not sure what I'm missing. So far I've only tested this with the Voigtlander 35mm f/1.4 Z. Maybe it only works with adapted lenses, but I'm not certain.
I'll play with it on my z5ii when I get home tonight. I know I was using adapted M lenses with the TTArtisans 6bit when I tried it a few years ago.
I was doing a little work avoidance and found this see if it helps. It says AFC and it's for the D850 but menus are similar.

So just to make sure I've got this right: when using a dumb adapter with no electronics, the camera relies on the Non-CPU lens data for FL, which is then used for IBIS. But if you are using any kind of chipped adapter, the focal length is supplied by the adapter itself, effectively overriding the Non-CPU data. Correct?
That would explain why all chipped adapters need to report a focal length, even if they handle it differently. It would actually be a really useful option if Nikon provided a menu option to prioritize the Non-CPU lens data regardless of whether the adapter is chipped or not.

Ok, I got this working using the Nikon D850 instructions you provided, not the earlier video.
The interesting part is that it does not work with Voigtlander native Z-mount or E-mount adapted lenses (Even when setting Focus Mode to AF-S). But...it worked perfectly with my setup using the Megadap adapter + Voigtlander dumb adapter + any Leica M lens.
________________
On the Nikon Zf:
* Set Focus Mode to AF-S or AF-C, either one works
* Set AF-S or AF-C priority selection to 'Focus'. (Only 'Focus' works, not 'Focus + Release' or 'Release')
* Set AF Activation to Off (instead of On)
Then:
* Go into 'AF-ON only', press right, and set 'Out-of-focus release' to Disable
________________
That's the key step that makes trap focus behave properly.
With this setup, I can use M lenses with trap focus. Basically, I fully press the shutter, and the camera only takes the shot when the subject hits perfect focus.
I'm pretty confident this should also work with other chipped adapters like TTArtisan 6-bit or SHOTEN.

You got it right.
Nikon developed the non-CPU lens data table for truly dumb lenses, simply so we could have good EXIF and the IBIS would know what it’s working with.
What drives me nuts is now that we can hard code this data into the camera, we shouldn’t even need chipped adapters for focus confirmation, as the camera has all of the same info it needs to support focus confirmation on a dumb lens. Nikon would make a whole bunch of us VERY happy if they allowed for this.
The moment you put any lens or adapter with contacts onto the camera, the camera will completely ignore the current non-CPU lens entry you previously selected.

I will post a photo with the Leica 35mm f/1.4 Steel Rim soon, but I can already tell it’s going to be a great combo.

Yes, they may simply not have that feedback yet. It would be much cleaner if they added a simple On or Off option like "Prioritize Non-CPU lens data". That way, the user can decide, and it removes a lot of the guesswork.
I'd definitely take the time to enter all my lenses and be done with it. For IBIS to work properly, all you really need is the focal length in the Non-CPU data (for those who don't want to spend time adding more info). Maybe Nikon is a bit more responsive to feedback than Fuji.

ZF's AF is pretty decent for wildlife right? If I get it, it will be mostly for 100-600mm range. It's a bonus that it can bring a different experience with M glasses.

I think it would be good, but there are probably more experienced wildlife shooters than me that should weigh in. I've shot kids Ultimate Frisbee games, skiing, and my dog running at me and it did really well. I'm sure z8 would do better, but except for all but demanding BIF I bet it would suffice.

Nikon Zf + Voigtlander 35mm f/1.4 Nokton Z using focus confirmation.
It's a bit unusual that the Cosina lens doesn't show 'Voigtlander' and 'Nokton' in the EXIF. On the Zf with the Z mount version, it simply records '35mm f/1.4' instead.
The Zf has great DR, I would say similar to what I get with my Sony cameras. Not really surprising, since it's likely using a modified Sony sensor underneath.

Same 😂
I decided earlier this week, after days of searching ZF colors and accessories, that if I get a ZF, I want a silver moss green. Then, once Fred posted photos of his, I checked and learned it was backordered. If not, it would have probably been ordered that night.

I think they only had one left, because right after I placed my order, it showed as backordered the next hour. No regrets though, I think it looks beautiful, even if I also like the all-black and silver versions.
the green leather feel great on the grip and back LCD.

That's hot. Without the CF adapter, it would look even more seamless. What filter did you put on the SR? I'm looking for an UV filter without front thread. I hand grinded down a 39mm UV filter for the Omnar 35 to keep it as small as possible.

Yes, the VM-E Close Focus Adapter II isn't fully silver, but in my experience it has the tightest tolerances, especially when it comes to centering, which matters a lot with these macro adapters. It also weighs just 72 grams, so paired with the Megadap (~40g) the whole adapter stack comes in at around 110 grams, which is still very manageable. I like that it has the black focusing ring, since it matches with my black M lenses as well. The Zf is mostly silver but has enough black accents that it still fits aesthetically.

Exit pupil distance, or lack of, is I think the nub of the matter behind non-cpu lens data / chipped adapter dichotomy.
