Assuming that you mean there are not any prongs or ears on your lenses, they are most likely E-type lenses if they are Manual focus lenses or early Autofocus lenses, both of which are safe to mount on your cameras. Why don't you copy down the information from each lens and list it for each lens in your reply. We can then determine what lenses that you have. Posting an image or two of each lens would be helpful as well. Good Luck and Enjoy your Nikons!
