Hi everyone,
thanks for this amazing collection of info and images in this thread!
I have a question for Jman13 or anyone who is using the E-mount Voigtlander 21mm f/1.4 on a Nikon Z camera (I have the Z7II and Z5II)
I bought the Fotodiox "Fusion Smart AF Adapter" (Sony E to Nikon Z) and was expecting for aperture info to be passed through to the camera - as there are electronic contacts and all.
I have some Nikon-native Voigtlanders, and when I turn the aperture ring on those, the aperture-info in the viewfinder is updated accordingly (and exposure settings are adjusted if I'm in aperture-control)
Is this what should happen with an E-Mount lens on a "smart"-adapter too?
When I turn the aperture ring on the adapted E-mount lens, no update happens on the camera side.
Do I have a defective adapter? (it was bought "used" directly from Fotodiox)
Or is this just how it works?
Sorry, this is my first time using an adapter... Just want to make sure I'm not having the wrong expectations

So my Voigtlander 21/1.4 is here, and as I mentioned I'm adapting it to my Nikon bodies. This lens is VERY finicky about the adapter thickness when used on Nikon. I tried with my Megadap adapter, which works great with my AF lenses, though it is slightly thinner than the perfect flange distance. And the Nokton was ABYSMAL on it. Sharp center, massive field curvature that meant the edges were utter trash if focused on the center until about f/5.6, and then they were only fairly bad.
Put it on my Fotodiox E to Z adapter, which I have but generally don't use because it isn't nearly as good at AF as the Megadaps. That adapter is thicker and with the Nokton, makes the infinity stop dead-on infinity. (and interestingly it was too thick for the Loxia, which couldn't reach infinity on that adapter, though I think a lot of that is the super-thick gasket, which meant it didn't mount well on this adapter either, due to it's slightly recessed construction).
On the Fotodiox, the 21/1.4 is great. Probably not quite as good as it would be on a Sony body, but sharp in the center wide open, reasonable edges, a bit soft in the outer midzone due to the wavy nature Fred mentioned. Stopped down to f/2.8, and it's quite good, even in the corners at 45MP, and very good on 24MP. At f/4-f/5.6 it's essentially perfect. Crazy how much very minor flange distance variations seem to make such an enormous difference in image quality with this lens.
