wow, that to me is wonderful footage, I just wish mine was half as good as yours...even before the crazy speed problem my flicker was awful, even when setting exposure manually....I have a bolex rex 1 and I love that camera except for the winding, that's why I bought the scoopic. I am thinking maybe the problem lies somewhere in the circuit board, the filming amp to be exact. I have a work manual and the schematic shows an integrated circuit on the board that is part of the filming motor's feedback control, along with diodes, resistors and such. that IC has transistors made into it and maybe one of those is bad or something, anyways I think off to du-all it goes......hopefully they have experience repairing the boards if necessary....thanks for the replies...
