The are identical. I have one of each, as far as I can tell
the Xenar in my Rolleicord is the sharper of the two. I also
think the Rollei Xenar is about the same in performance as the
Rollei Tessar. A lot depends on how well the camera is aligned.
The difference in price was due mostly to the lesser amount of
machinery in the Cord.
Also there is a lot of other stuff between the taking lens
and the results on digital media. That is, who knows what you are
really looking at.
You really need to set the lens up in an optical bench and
look at the aerial image with a microscope. I am not kidding.

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.
