Note that "Maximum LV Aperture" doesn't work in the high-speed continuous modes C15/C30/C60/C120, which means it also doesn't work for pre-capture. I expected this but it's actually not documented in Nikon's FW 3.0 addendum. Since those modes use the video pipeline of the camera, they keep the aperture stopped down to the shooting aperture, just like in video. This is probably a necessity even without the video pipeline being used because the aperture wouldn't be able to cycle fast enough on most lenses for the fastest rates.
Note the camera still lets you enable the "Maximum aperture LV" in this mode - it just doesn't honor it.

Could someone enlighten me as to how the subject detection works with manual focus lenses?
And which lenses is it compatible with?
I have a few MF lenses with CPU (Zeiss ZF2, voigtlander) and wondering what to expect
I think any chipped lens will support this feature either natively or via the Nikon FTZ adapter. Works well (as with the Zf) with my Z-mount Voigtlander 40/1.2 lens.
It works exactly the same way as with AF lenses except you have to focus. It detects eyes, animals and all the other stuff - the focus box goes there and when you hit focus the box turns green.

ahh ok i found the problem. you have to enable it for manual focus mode in new menu setting "MF subject detection area".
I was hoping that when you zoomed in, the zoom area would follow the eye point but thats not the case. It just puts a focus point that moves with the eye of subject and goes green when in focus.
this was with a zeiss zf.2 lens, seems to work fine

The actual MF subject detection feature is compatible with all MF lenses, regardless of whether they are chipped or unchipped.
Only the focus confirmation, box turns green, requires communication between lens and camera, but everything else also works with a dump adapter and MF lenses without electronic communication.

Sounds weird - with a chipped lens zooming in should take you to the area of subject detection.

Yes, hitting magnify with MF + People detection will punch into the detected eyes/face.
It does, but what i was hoping was that the zoomed image would track the focus point; the eye stays in the same spot in the zoomed area if the subject moves.
That's not how it works though.
It doesnt have any focus indicators either when zoomed in which is a shame
anyway not the end of the world, just trying to figure out how it all works. thanks

There’s no need to zoom in if you have focus confirmation which is probably why they don’t display while zoomed.
It’s more for ensuring critical focus via focus peaking.

greetings,
i recently updated my Z8 with the new V 3.0 firmware update. i read online discussions that indicated few had problems with older nikkor lenses attached via the ftz adapter. i guess i'm not so lucky. my AFS nikkor 24-70mm lens has lost all aperture functions after updating to 3.0.
can a technical person respond with a possible solution? can i re update to the older version? change a setting or something?

Being able to roll back to 2.1 saved my butt. The night before I left for vacation I updated the Z8 to 3.0 so I could play around with the focus stacking and I got to the beach and the AF wasn't working on my Tamron 50-400 (the only long tele I took). Interestingly AF still worked on my Sirui 85mm 1.4 and of course my Nikkor lenses.
But being able to roll it back was a life saver as I ended up using that lens for almost 90% of what I shot.

Can anyone here confirm that the option to cancel subject detection in manual focus with a Z8 only works with chipped MF lenses?
I played around with my Z8 and some MF lenses today and it works without any problems with my 35mm Apo Lanthar Z, where I can use the subject detection hotkey, which I have assigned as a subject detection kill switch, to subject detection off.
As soon as I use an MF lens with a dumb adapter, the hotkey doesn't work, and therefore I can't disable subject detection via hotkey.
Subject detection also works with dumb adapters and non-CPU lenses, but unfortunately the hotkey assigned to subject detection off does not.

For the information of other Z8 users with non-CPU lenses, the situation has been clarified.
The Recall Shooting function (RSF + RSFH) doesn't seem to work at all with a non-CPU / dump adapter lens.
So it doesn't work with spot metering either and also not with the other functions that can normally be assigned with RSF/RSFH.
That's a clear indication that communication with the lens is necessary for the Z8's RSF/RSFH to work.
Zooming in also works with a non-CPU lens in manual focus mode when subject tracking is activated in MF.
As with a chipped MF lens, you have three MF subject detection areas to choose from: All (tracking the entire image field), Wide S, and Wide L.
Once subject detection is active and has tracked something, the zoom takes you directly there, no different from a chipped lens.
The zoom modes also all work with non-CPU lenses, 100%, 200%, and now also 400%.
So even with a non-CPU lens via a dumb adapter, there are no differences or restrictions compared to a chipped MF lens such as the Voigtlander Apo Lanthar Z.
What does not work with a non-CPU lens is focus confirmation, i.e., the frame of the focus box turns green to confirm focus + Recall Shooting function won't work.
Unlike with my Apo Lanthar Z, where pressing the RSFH hotkey instantly deactivates subject detection and pressing it a second time instantly reactivates it, nothing happens with the same hotkey/assignment on a non-CPU lens.
You have to go through the menu or use a hotkey with "My menu first entry" to deactivate or switch MF subject detection.
