Also, WTH with the focus and zoom rings being so comically different in size?
Makes a lot of sense to me. How often do you manually focus vs zoom the lens?
I don't see a motor drive or aperture lever in the adapter, I think that one is still needed for the tons of "D" lenses with motor drives. If Nikon abandons them, I think that they will lose some customers. Perhaps a adapter is coming for the older lenses later.
The bulges at the bottom and on the lower side indicate to me that the adaptor contains a drive motor for D lenses.
