Here are some nice rarities I found localy in Ukraine. Era-12, Era-14 and Era-15
They are still at my friend's home, he did the photos, but I wonder if one of you had more infos about it.
I only found infos in Volosov's big book "Fotografi4eskaya Optika" It was designed by E. Grigorieva, I. Driatskaya and S. Frolova (3 women). It was kind of high end reproduction lenses with very high resolution power. Lens design is 6 elements in 4 groups.
Pity, it's not written when they have been designed. Bt in the book, Volosov say that "during the last years[...] was asked to develop high resolution lenses" (sorry, very fast traduction). His book was released in 1978, so I believe that my exemplars are close to first years. Anyone one have more info about it? Date of conception, for what machine / camera it was designed?
