Welcome to Nikonians! It has been correctly stated that the Nikkor 55mm f/3.5 P is a Pre-AI lens that must be modified to AI spec in order to be safely mounted on your D7000. It has a 1:2 reproduction ratio alone or a 1:1 reproduction ratio with the M1 or M2 extension ring. Good Luck and Enjoy your Nikons!
