Once in Prague, I bought a Leica II copy with the thought that even though a copy, I would put a film through it and see what it was like. I was not impressed, as the optics were quite poor and when you wound on it sounded like two bits of sandpaper rubbing together. When I got home I compared the build quality with an original Leica II under a powerful magnifying glass and the difference was phenomenal. Any others experience such a comparison of copy with original?
