But, in this case, the lenses made by Canon and
Nikon between 1947 and 1952 were exact duplicates
of Leitz and Zeiss lenses, made from German
designs and German optical glasses supplied by
U-Boat in 1943 -- I can did out which U-Boat made
the run to Batavia if anyone is curious. There
were only two differences -- the Japanese mounts
were made from scrap aluminium and were not as
strong as their German progenitors, and, from
1951, the Japanese lenses all were coated with the Smakula vacuum coating.
The GT-40 made by ERA are not regarded as
"copies" within the car community: they are
"developments". The 1.4/50 Nikkor introduced in
1954 was a development of the 1.5/50 Nikkor of
1948. But we are speaking of the 1948 lens and not that of 1954.
