Good perspective on the cameras varjag, thanks for that.
Not to go too entirely off topic, but I never said the AK was not competent and reliable and realize you know that. I too know them to be both extremely competent and utterly reliable. Even the Hungarians. I have built both AMD-63 and 65 variants from demilled parts kits and the workmanship is on par, if not better, than some Russian rifles. Same goes with some of the Polish rifles. Chinese rifles, though not licensed and made to the same physical dimensions and specs, are also known to be very good, with the exception of a few well known commercial versions made for export. The Russian Kalashnikovs I have seen (a '71 AM Type 3 milled rifle, a Russian '73 RPK, and countless SAIGA rifles and conversions based on the SAIGA export rifle) are all exceptionally well made. But what I am speaking of is elegance and finesse. I do not believe the Kalashnikov nor the FED and Zorki that I have are "elegant" nor are they designed with those touches of finesse that make one say "wow, that was a great idea and a brilliant design decision". Indeed they are sort of chunky and clunky.
I DO however, believe that is part of their success, from the Kalashnikov at least, contrary to popular opinion, they CAN break but they can also be fixed easily. They are over-built and well engineered. From a newbie's perspective, the FEd and Zorki both seem to have that same overbuilt feel. Perhaps that is unfounded, but first impressions at least seem that way. Your post indicates they are not in fact analagous to the Kalashnikov, and that's fine, I'm speaking on terms of impression.
Having not run many rolls of film in these, I am ignorant in this area, but will surely be learning!
