Hi and thanks for your comment.
Are you sure that Zeiss ZE lenses have aperture rings? None of my Zeiss ZE (28/2, 21/2.8, 35/2, 50/2 Macro) has it 🙁 I think that Nikon ZF has it, but there is no electronic adapter for Nikon.
Otherwise I agree that if you get used to wo focusing in low light, it might be annoying. Maybe there is some work around, I didn’t think about it, because at low light levels I used lens wide open anyway.
On the other hand, real manual focusing with hard stops is a gods gift in the dark, when all you need is to focus to infinity.
