The Z mount 50mmF2 APO-Lanthar passes the in-focus information and f-stop (must set manually) to the camera, the camera's AF patch , [ ], turns green when focus is acquired, AFS, not for AFC.
The M mount lenses are 100% manual. Adapters, LM-Z are available to implement AF but I have not used one, and yes, they are $200-$300 from what I've seen. None of my M mount lenses are chipped, the adapter has no electronics or contacts.
I prefer doing manual AF with M mount, focus peaking is great, and I have the Video Record button set for 100% zoom (FP does not work at 200%, at least for me). Coarse focus, zoom, fine tune, and click - in less time than it takes to read the steps. Now if you're shooting grand-kids, sports, or street, you'll probably use zone focus which is another story.
I don't think any of the AF tracking features are available with Voigtländer lenses. Perhaps someone else can provide more information?

I’ve been told that adapter doesn’t read the lens chip. One that does is a few hundred.
