The Zeiss Jena lens design had not evolved beyond the 1937-38 era,
and in the years Zeiss was struggling to re-establish itself in Germany,
the MacArthur Vice-Regency of Japan helped clear the way for Nikon. Nikon seemed to overlap
the Zeiss versions (take a peak here: http://imaging.nikon.com/products/im...kkor/n34_e.htm)
So BOTH the Opton and 1.4 Nikkors were well evolved designs by the mid '50s.
Although they both derived from the mid '30s Bertele design,
they both were well beyond it. And for both, time was running out on the Sonnar-as-normal-lens,
for it was a very difficult lens to manufacture,
and the Double Gauss / Planar / Xenotar offered both design and manufacturing advantages.
