Steve. You understood correctly. I have 5 different lenses, so if I change lenses, do I have to go to the menu each time and change the lens settings? This sounds like a real hassle. I know there is a Nikon chip you can buy. I wonder if that will help matters? Do you use the Nikon chip or is your adapter totally unchipped?
