I sent an E-Mail describing the situation to photo AT zeiss.com
and got a prompt reply today. Here is the answer translated by
google:
Is it really a Aussprung in glass, or simply a dirt (or other dried
liquid?) Have you already tried to clean the front lens?
If it really should be a damage in the glass, this is probably due
to an influence from the outside passes (shock, shock ...). Such
damages are not covered under the course warranty.
The replacement of a front lens when Biogon T * 2,8 / 21 ZM is
about 150, - Euro cost (net). Please understand that without a
complete review of our service can not predict binding cost for
repair.
So they mixed up the 35 with the 21 but the happy news is that
they were right ... I tried to clean the spot with cloth and a
lenspen before but this time (while chuckling at their assumption
that it might just be dirt) i tried again and used my fingernail to
rub over the mark and ...... it vanished! :bang:
