The Fringer NF-FX adapter arrived today!
I've tested it on a Nikkor 18-200mm G VR and a 50mm 1.8D. Everything works great on the zoom: autofocus, aperture, VR. The 50D doesn't autofocus (it's not supposed to) but aperture is controlled from the camera. I also have a few other Nikon lenses I am keen to try.
Very exciting!
