I noted the mentioned "Your choices are Nikor T- (360), 500, 720 (interchangeable rear lens elements)" directly relates to my question. I have been looking for some information on a lens I just acquired a 300/500mm Convertible Symmar. I would think that these types of len came with an interchanging rear element to use when changing telephoto?
