Hello Jan:
I understand your point taking in mind technical issues,
however glare is part of the charm for this kind of backlits and the reason
some people liked it in Flickr; the lens produced good contrast and
sharpness for some areas. The subtropical sun itself in the picture is a
severe test even for a current nanocoated lens from the digital era., These
are old lenses, in general we don't know their life along decades and
differences are more from the current condition than from design and
optical treatment, I can see excellent images from these lenses in books
printed at the time, I think they need a bit of tolerance today.

Hi Carlos,
Very interesting. Looks like this T-coated 2/50 Sonnar still has the same
glare issues with backlit subject my coated postwar Contax 2.8/35mm Biogon
had, which I since sold. Zeiss clearly improved the coating to the T* level
after the war.
Wonder how a 2/50 Sonnar or 2.8/35 Biogon from the last production year
(1961?) performed?

I bought a pretty rare lens "Carl Zeiss Jena Nr 3006362" T coated eight
years ago and I had never used it. It's part of one of the firsts T coated
lenses batches made at Carl Zeiss Jena after the factory destruction during
the war, in March 1947; the manufacturing had something to do with Soviet
technicians training to manufacture the Contax camera as Kiev in the Soviet
Union, but I don't recall details.
Yesterday I put this lens on the Contax II 1937 loaded with an outdated
Ilford Delta I kept in the freezer and took some photographs, developing
the film with the Romek PQ7:
