look at the bottom of the page - there is a optical design of C Sonnar T* 1,5/50 ZM
and now look this

does this design look familiar to you?
i read on first link that j17 had floating front elements like in new sonnar.
too bad they didn't have serial production of this, and also too bad they didnt do that to j3 also. we would have advanced sonnar 1.5 40 years ago.
