Thanks Mazurka for your input :
"This lens had the "Carl Zeiss Ultron" moniker probably because it was originally a Voigtlander design. Most lenses made for the Icarex had Voigtlander lens names, except for the Tessar, Pantar and Distagon which bore, of course, Zeiss trade names.
Hence, even Zeiss had bought out Voigtlander by that time, they seemed careful to distinguish lenses having different parentage."
There was another lens for the Icarex named after Voigtländer: the Super Dynarex 135mm f 4 but I´m not sure it was identical to those designed for the Bessamatic/Ultramatic series.
What I can remember very well about the Ultron 50/1.8 was an official Zeiss statement about this lens published in an old Argentine Photo magazine (hope I can find that issue!) telling that this lens was designed after the ZI- V merger and was one of the first (if not the first) lens designed with the aid of computers. The article mentioned also that the concave front lens was a result of the design method (software).
Other than keeping parentage, I´m sure there was some pressure from the Voigtländer side at the time of choosing lens names, specially thinking that
all the other lenses (but one) for that camera system were Zeiss designs.
Cheers

Actually the Icarex/SL706 "Carl Zeiss" lenses were manufactured in Braunschweig in the Voigtlander lens plant, like the "Rollei HFT" SLR lenses some years later.

Thanks guys, what I saw had, what looked like copies of Zeiss drawings with glass type and barrel dimensions - as well as some sample shots with these lenses. I just thought they were amazing construction and optics - dreamt up 70 years ago.
I am usually a bit lukewarm towards to complex lens diagrams - but these were interesting. Dont think I would want to make them though! The Sphaerogon looks astonishing!!!!
