[rollei_list] Re: 2.8 80mm Opton-Tessar

Richard, the Tessar for the Baby was a 2.8/60 and for
the 4x4 format, I mentioned this lens in one of my
posts, I guess that the prescriptions are different.
It would  be interesting to know why the baby 2.8/60
was not manufactured after the war, only the 3.5/60
version, if the lens was so good it would be better to
choose the 2.8/60 and not the 3.5/60.-

All the best
Carlos
