I am trying out a couple of Nikkor AF Nikkor lenses with Zf via the FTZ II adapter.
The problem I am having is that the camera is demanding that the lenses be set to Auto Aperture.
One of the reasons I want to try the lenses is to be able to set aperture via the aperture ring.
Does anyone know what setting have to be changed in the menu to make this occur.
I found a YouTube video about changing a setting on older Non-Z cameras but can't find anything similar on the Zf.

Any thoughts?
Most likely you will have to use an adapter without electronic connections, or disable the connections with tape.

This is just how it works with a chipped lens on a chipped adapter. You have to use a dumb adapter to manually use the aperture ring.
Wait, does it mean Voigtlander F lens aperture ring won't work with FTZ too?

Does it have an Auto setting option? The lenses I'm testing are Nikkor lenses that have an option to Lock the aperture at its minimum setting. This permits the aperture to be controlled via a dial on the camera body.
If the lens aperture ring is not locked in Auto the camera gives an EE error message and won't work.
Chipped F mount CV lenses have to be set at min aperture and controlled via command wheels . You cannot use the aperture ring. Z CV lenses you can use the ring to control.

You change aperture with the camera command dials just like on any other lens.

So how does it work? if you need to set ring to minimum and adapter cannot move aperture in lens, how does it work? I must be missing something...

The adapter does have a motor to move the lever that controls the aperture relative to the maximum. But it can't read the setting of the aperture ring. These require separate mechanisms. The aperture readout mechanism is somewhat fragile and expensive (I had my D700's aperture readout mechanism break after the camera (with lens) fell on a hard surface from a height of 15-20 cm.)

which adapter has a motor? you aren't referring to the ftz adapter; are you?

Motor to move the aperture, not motor to drive autofocus. The FTZ adapter has the former, otherwise you wouldn’t be able to control aperture with G-type lenses.
What it doesn’t have is the aperture index mechanism (what Ai stands for in manual Nikkor lenses), thus it can’t read what the aperture is set to on the lens. Afaik this is not a motor, but a spring-loaded mechanism. Otherwise wouldn’t work on cameras like the Nikon FM without battery.

Aaaaah, ok, now I see, so it has a motor, but cannot read the values.
Great...
So when using Voigtlander Z lens, I cannot use aperture ring to control the aperture? Or can I?
I thought you could and that would make Voigtlander lens only lens with aperture ring that can be used as Z lens.
Well, I thought you could use ETZ adapter and use aperture rings on E mount lens too, right?

Here is the way I am interpreting Z camera aperture control;
A) if the lens expects the camera to control the aperture the camera will do so via a control dial.
B) in the case where the lens has an option for aperture control via a lens aperture ring, the Z camera firmware must provide an option to select the aperture ring as an alternative to the control dial. The Zf, and perhaps other Z cameras do not have that option available. It is available on older DSLR camera with the F mount.
C) if the lens has an aperture ring and no electrical contacts to link to the camera for aperture control the camera shows F — and the lens aperture ring controls the aperture.
I have Voitlander and Laowa lens that fit into group C. The Nikkor lenses I'm testing fall into group B. A canon TSE lens I have falls into group A. (This lens requires an adapter that provides electrical contact between EF mount lenses and Z camera bodies.)

B) is not a firmware limitation, it's a hardware limitation of the FTZ adapter. Z cameras have no way of knowing what the aperture of the adapted F lens has been set to, whereas F-mount cameras with aperture index tab do.
Voigtlander Z lenses close the aperture manually and report the value that has been set electronically, that's why the aperture ring works for them, but not for adapted F lenses. Those Ai-P lenses (manual focus, but with CPU) only report their focal length and max aperture to the camera - bascially the information you would otherwise set manually for older Nikon lenses without CPU.
