The use of Xenars on Rolleis spans decades. The basic design is the
same on all (tessar-types) but with that kind of time frame, it's
possible coatings and glass types changed. When a glass type is no
longer available, often the lens has to be recalculated. This happened
with the Rolleiflex T Tessar at some point after the war... I think in
the 60s...

Is the 3.5 xenar installed in rolleicord the exact same lens as the 3.5 xenar
installed in Rolleiflex? looking at the results of the two on Flickriver, I
always perceive that the group of photos from the Rolleiflex seem to include
a higher number of photos showing very good contrast. I wonder if it is just
my imagination.
Best,
