Testing my Zenit 12 with different M42 mount lenses, Jupiter 9, Pentacon 135, and Porst 55 mm.
I used the cheap and low quality Ferrania Solaris 100 film. A wrong purchase. It will be better with a fake Kodak Gold made in China, sure.
The cam works fine. The exposimeter not so fine with alkaline batteries. Next time I'll put in use my manual exposimeters.
But for the moment I see this cam works propertly and it's only asking for a good quality film.
