Hi Luiz, no my camera is completely different. The one in the last link has a built-in Moment-24C shutter inside the back, it is clearly military issue as it came directly from an airbase warehouse in Ukraine.

Cheers,
Vlad.

oh and mine is the size of Zenit, so I strongly disagree with your assessment, my friend! [:D]

hello Vlad
You are right! but your camera falls in the same classification critereia: "camera for working in aggressive environments, (and possibly produced by GOI)"
One can feel similar (and heavy) construction rules although not identical shape.
