... nobody ever talks about acting around here anyways...
Go start talking about camera and lighting in a discussion on an actor board and see how fast you're shown the door for being off-topic and unwelcome. You do it thrice here with your tangent about some specialized lens, not to mention ADR, that has nothing to do with anything going on here and/or irrespective of the reality of this project and where it is in the process of completion (ie. not completed). Trying to force a confluence of other subjects is both presumptuous and selfish. This is a shooter's board for technical discussions. This is an image-centric article about an anamorphic film in post-production. Maybe you should start a blog or something, maybe, and get this stuff off your chest in a more appropriate venue?
Anyway, on topic, so the interface between lens and camera wasn't tested is what you're saying. You're taking it on faith that it's both free of human error (pretty unique feat, regardless of pedigree) and also manufactured with the forethought that it just might be used with very, very rare anamorphic lenses that functionally depend upon a correct and precise up-vector, ignoring the skew in the raw imagery that had to come from somewhere other than the camera (a reasonable assumption, though it should also be eliminated from causation)?
Forgive me from being too analytical but solving these kinds of problems based on the number of places error can be introduced (here we have two cameras, two adapters and multiple lenses, nominally) is just kinda what I do and I have a hard time turning it off. I come from a background where if I didn't figure out the problem it was likely never going to be fixed. There aren't that many factors here so isolating the problem is really easily and quickly done, but to do it you have to get over any notion that any one of the pieces involved could not possibly be behaving in a way that's inconsistent with your expectations.
"Professional" equipment is as likely, if not more likely (by virtue of being one-off or low volume) to malfunction or have some kind of issue. You quickly learn this the more you're exposed to it.
edit: Regardless of all that, I do applaud any filmmaker who goes for it. I don't think even close to half of them lucky enough to start their film, as an independent, see it through to getting it in-the-can. Fewer still begin post production and even fewer still make it through editorial to arrive at a completed film. Keep at it. Every step is a reward in and of itself and fuel to keep pushing forward.
