Unfortunately I have been unwilling thus far to write a decent piece about the Zorki-S, the most obvious reason being that my 'C is extremely shabby and therefore not of vere inspiration to my inner writer. It is to be hoped, therefore, that future productivity will rise and that until that goal has been achieved, morale will stay high and unbroken.
For now I offer you this: how to open up the Zorki-S.
And (update) this: visual instructions.
However, I have high hopes for the future. We all must vivaciously work together to once more bring glory to what may at times seem a forlorn enterprise. I am however confident that my trust will not be betrayed.
This isn't good: a shutter you can see right through. Trademark of overuse and undermaintenance. If you want to buy an old Leica copy like this, you should screw it open beforehand to check for this kind of defect.
Soviet workmanship: this Zorki-S has an unequally polished film beam. Or actually the polishing is correct, but the casting is irregular. Net result: the camera is built to spec, but it doesn't look that good.
