lol.I went down the russian rabbit hole too, first buying LOMO super speeds on the cheap, then buying Konvas Bodies before shifting to rebuilt KINOR 35h from Anders Banke and then converting the camera to two perf at Aranda! Just as the RED Digital Craze hit, and the SAG threatened strike caused a shift in production to Digital and a big move to the east coast. As the Film demand decreased so did the labs, until the last lab in NYC closed. That was the absolute bottom, and the price of Movie cameras dropped to nothing. All of the sudden what i paid for one Kinor 2 perf camera I was able to buy four more....lol. At that point i had all these KINOR camera's that where hard to service and no one wanted to use. SO i have a nice museum of KINOR 2 perf sync cameras lol! However once the hollywood heavies came to the rescue and Kodak emerged from bankruptcy and opened a new lab in new york, the price of my movie cameras started to sky rocket, lol. Maybe i should open a 2 perf camera store, lol!. Anyway after all that, i finally decided i needed cameras that can be serviced and are built to last, so now i have 2 perf ARRI bl4's and an ARRI III. Finally doing test, until COVID hit and closed down the lab, lol. I can still look at my russian two perf museum lol!
