The chipped Zeiss and Voigtlander lenses are AI capable and since they are chipped they will communicate with the camera body just like Nikkor AI-P type lenses. Therefore all exposure modes P, S, A, & M are possible. You are correct that the electronic rangefinder will assist with Manually focusing the lens. Good Luck and Enjoy your Nikons!
