I just acquired this peculiar lens. The person selling it wasn't all too sure what he had either.
On the surface it looks exactly like an "RO2-2 Kinooptika 75mm F/2". On the inside it also looks exactly like that lens. It's got the right elements in the right groups and the correct amount of aperture blades. Here's the issue though. That lens was only manufactured in one lens mount for the AKS-1 cine camera. This lens is not just L39/M39 mount, but it's also properly rangefinder coupled.
There is another issue here, besides the peculiar mount. It doesn't say RO2-2 or Kinooptika anywhere on the lens. Instead it features "МОСКВА" written upside down in the lens ring (this lens is supposed to be made in Leningrad) and instead of RO2-2 it is marked "МКИП".
Finally it is marked with a serial number 47. I checked if the rest had just wiped away under my microscope, but there is nothing else engraved (while the 47 is engraved). God knows why it's only marked with a 47 and nothing more.
(Moscow/KMZ would be accurate if it were the RO2-2M or later RO2-2 KMZ version, but the cosmetic styling does not match either of these more modern lenses. These lenses would also have been marked with the KMZ factory logo and not just Moscow)
Could someone here please shed some light on what I have bought?
