I would also say that you don't even need a speed booster. Fast glass like Voigtlanders, SLR MAGICs all give you a s35 look to my eyes.
You are absolutely right.
And while we are at it, forget the DIT, skip the sound mixer, the hell with the line producer, and why even bother to light anything, that way shooting with 3 cameras at once all the lighting will match.
There are are a number of paths one can take when producing a feature film that I would not journey down.
No offense to the OP, but shouldn't the choice of camera for primary photography not be dictated by A: The line item budget, and B: the Director of Photography and Director choosing the best tool for the project within A, rather than "no offense" camera fanboys?
