Has anyone considered the thin filter conversion Kolari offers for the ZF? I can't decide if it would be worth the effort. I typically shoot 28 or 35 M mount glass.
I'm absolutely planning on it at some point when used Zf's come down in price!

I like a little vignette too, but this isn't a very pleasant one. It's a sharp darkening of the corners that you'd probably prefer to crop out.
After posting, I dug out the adapter (K&F, by the way) and stuck a bunch of lenses on it. Nothing scientific, just looked at live view with the lenses facing a blank wall.
Lenses with visible vignette at all focus distances, zoom settings, and apertures: pre-Ai 55 f/1.2, 35-200 Ai-S, 35-105 Ai-S, pre-Ai 135 f/2.8, and pre-Ai 50 f/1.4. The 180 f/2.8 ED Ai-S also shows it until you focus further out than about 20 feet.
Lenses with no visible vignette: 24 f/2.8 Ai, 28 f/2.0 Ai-S, 28/35/50/100 Series E lenses, pre-Ai 5cm f/2, and pre-Ai 105 f/2.5. The 55 f/2.8 Ai-S showed none, except for a very small amount just at MFD.
Now I'm curious to try another F to M and see if actually makes a difference. I got the adapter just for the 55 f/1.2, so once I noticed the corners I stuffed it away and didn't try anything else. But seeing that the 28 f/2.0 and 105 f/2.5 seem to work, I think I'll start using them on this setup instead of the FTZ. ...Show more →
I use an Urth branded F-to-M adapter which vignettes with the 50mm f1.4 Ai-S (but not with the 28mm Ai-S as far as I can tell). A shame because it’s otherwise a well made adapter.

Thanks for checking. Sounds like some lenses just adapt better to M than others.
I got a few minutes to try the 105 with the dogs today, and I have to say I really like this combo. The K&F isn't necessarily anything special, but it feels like an extension of the lens, unlike the FTZ which is a bulky, slippery, plastic eyesore. Same goes for the TTA, which seems like an extension of the Zf. Of course confirmation is great to have, and IBIS seemed just fine considering the adapter is reporting 90mm.

K&F adapters are the best dumb adapters for looking and feeling like extensions of Ai-S era lenses for sure, and cheap enough to buy one for every lens.

Will using Nikon's FTZ II give focus confirmation with AI-s lens?

No. The lens itself needs to have electrical contacts to pass on info about the lens. The FTZ having contacts is not sufficient

Not true, cause you can use adapter with contacts and lens without and get focus confirmation - TTartisan M to Z gives you confirmation with CV VM lens.
This is why I'm asking about Nikon's FTZ adapter, would it work? Can you confirm it from your experience?
p.38 #10 · Nikon Zf as a platform for adapted/native manual focus lenses
I note for the Z8, that simply an adapter connected to the body with electrical contacts seems sufficient enough to enable the working of the focus box.
It doesn’ t require the complete path to have electrical contacts.
I just tried this, using the Fringer EF-NZ II adapter which has contacts on the Z mount side, simple no contacts EF-LR adapter, Leitz Wetzlar Summilux-R 80/1.4, no contacts, and focus box works on my Z8.

I already answered you on the FTZ question. It does NOT give you focus confirmation with dumb lenses.

Anomaly?
Shrug...
The focus box always works with eye-AF on a dummy adapter, but you only get the white box. No green box focus confirmation.
Green box focus confirmation requires the camera know what lens is attached via the contacts on the adapter. Some adapters pass through the data from a chipped lens to the camera. Some adapters fake this process by letting you dial in a focal length physically on the adapter.

This is with the Z6_3 but similar function so it makes sense-
I went out Saturday night with the Z6_3 and the LEica 50 Lux attttached with the TTartisans coded adapter- During the day- Perfect confirmation, no issues at all. At night it was struggling to get confirmation on focus. Prefer the RF patch for night time use. How are people using the ZF at night with adapted lenses? Overall very happy so far with the performance of M mount glass on the Z bodies!
A few shots although didn't take a ton that night-

I will have to test again, as I am always trying different things.
I remember the focus box as being green in this set up?

There’s no focus confirmation for dumb lenses with either Nikon FTZs. This is from my experience of using them. Nikon could enable it in camera firmware but choose not to…this could be for commercial or technical reasons.

When you’re having trouble in low light, are you still in one of the modes that allow subject detection? I would use single shot, no subject detection, smallest AF box.
But in low contrast situations, nothing beats having a function button set to 200% zoom and focusing by sight in the EVF.

RECONFIRMED:
On my Z8 setup below, my white focus box turns GREEN when the lens is manually focused to subject.

^ Is the green box still accurate? What focal length does the Z8 think is mounted or can that still be set manually? If the wrong focal length is registered, IBIS performance will be impacted.

Snippet from the manual:
I will check the settings information on the following page.
"To fix this, we added manual lens focal length input function."
3.4 settings for MF lenses without electronic contacts
Unlike Nikon FTZ adapter, when installed on Fringer EF-NZ adapter, lenses without
electronic contacts also get the green square focus indication at the focus point position.
When this function greatly helps a lot of manual lens users, it has a drawback. The Non-
CPU Lens Data menu item doesn’t work anymore. Without correct focal length data, the
IBIS function of certain Z cameras, e.g. Z6 and Z7, doesn’t work properly. To fix this, we
added manual lens focal length input function.
