You are, of course, correct, in saying that a well-constructed copy can be better than a poorly-made original. However, the Zeiss originals were extremely well made lenses and were, in fact, superior to the Nikon and Canon lenses in one important regard, that of the glasses used. (The initial production by Canon and Nikon did use Schott glass imported during the War by submarine, but this had run out by the early '50's, and the Japanese struggled a bit to establish domestic supplies of optical glass.) The German lenses were made from a broader range of optical glasses and, Postwar, Schott was breaking new ground in developing new melds. The Japanese were unable to compete in this and, for that matter, still allow most research in this to be done in Germany or the US. (Hoya and Zeiss have an arrangement whereby Hoya references some of its production to the Schott catalogue, for instance: Hoya is pouring Zeiss glass, under license.)
