I've seen under your replies, that you have a misconception of the professional photography market.
Yes, we make money with our equipment, either in direct billing or use. Yes, we need professional equipment.
NO, no clients that I work with in the last 5 or so years cares if I shoot with a Nikon, Canon, Phase, Leaf or Hasselblad.
In fact since our studio's line item every detail on an estimate, the idea of putting down digital dslrs, or digital medium format cameras holds no interest to the client, regardless of level, budget, brand name or genre.
There was a brief moment, back in the days of digital adoption where it mattered, but today, everyone that works, usually works from the bottom line number and up, not the other way around.
So my point, whether I chose to shoot with a 4k RED vs. a 2k Sony, a 31, 40, or 60 mpx back vs. a 36 or even 20 mpx dslr makes absolutely no difference to my clients. All they want is results and an invoice that reflects the estimate.
But if you want to impress a client, mount an R1 or a big Arri on a support with a large pl mount Angenieux lens. That will get their attention a lot faster than any still digital camera, because in the client's eyes, digital still cameras usually look the same and right or wrong perform the same also.
