I'm not surprised that BM hasn't made in-roads to the "full production" side of film-making.
There is a lot of hyperbole and irrationality when it comes to cameras and the economics of them. Most importantly, to this conversation anyway, are:
Once you have enough cast/crew that you have to schedule your shooting days then you're probably paying enough (even just in logistics) that the hire of a high-end camera isn't that much of your budget so you can afford whatever camera you want
I agree with @barefoot_dp comments about getting hired - if you're doing this to make money then start with that as the goal and work backwards, which looks like the FS7 or FS5ii are much safer bets
BM makes cameras with great specs for considerably cheaper than the existing incumbents in the market, but this only really matters to people outside the above two situations, such as:
Amateur film-makers who are shooting micro budget films with people donating their time, so need to own a camera because they can't afford to book camera rentals and then have cast/crew cancel on them last minute when it's too late to get a refund on equipment hire
People self-funding documentary work where the phone could ring and they need to get in a car and go in order to capture the action as it happens
Film students or people who are producing their own projects and who will use their camera enough for it to pay for itself over a few projects
Hobbyists who shoot at a moments notice or shoot a little each day for many days
I'm a hobbyist, so I care absolutely about what things cost and all the technical and image quality aspects of a camera, but in a business it should be viewed in a completely different way.
