I'm sorry, but my guilt light just lit -- for mentally admonishing the mentally handicapped:
"There is no joy in using the Voigtländers. The Voigtländers are practical, but not that much fun to use." Rockwell
My Cosina low-end RF is fun to use, gets the shots better than any other, but is starting to fall apart. Emphasis on falling apart: more Cosina junk.
How do we know that these new Cosina RF offerings are not junk? Well, we won't, not for a decade.
I think the better bet is to figure out what is wrong with the Soviet cameras, and attempt retro fix them.
