Yes, there's a version of the Novoflex F-to-Sony-E adapter that allows (stepless) aperture control with G series Nikon lenses. Allows you to use older lenses with aperture rings too.

I imagine that still excludes any means of using a G on a non-digital Nikon body such as the F3, since there aren't any electrical connections in the mount that I know of or have seen on that, though I can't be sure about the F4 which was the only one in the newer 'computer' series bodies that I ever bought.
I guess the introduction of the G is a declaration that the remaining film body, the F6, is dead, too, unless it comes with electrical connections in the mount which, as I say, I don't know.
As an aside: it would be nice if Nikon had made a pentaprism for the F3 that included a diopter adjustment wheel; I've long past the use of the last correction lens I bought, and without it, my F3 is pretty much lost to me now. But wait: the F4 pentaprism would probably fit it, and that had a diopter wheel! I can see another waste of money looming on my horizon with that thought!
