Am I wrong to assume that actual working cinematographers would have something to say here? Not saying that I'm one of these endangered species, but I'm specifically thinking of Bradford Lipson (Wilfred) and Jeff Jur (Dexter). Jeff Jur said in an interview, that most of the time the post production team had a hard time telling the difference between their A and B can and the Nikon D800, which is fair enough if it wasn't for the fact that the A camera was an Alexa.
Again, not claiming to be a cinematographer equally skilled to the above mentioned I think their on to something. Why else would two very successful cinematographers use them? If Blackmagic and GH2/GH3/GH4 are such amazing cameras why is that only amateurs and small businesses uses them and not big studios with budgets large enough to use whatever camera they like?
Nothing bad about mr. Reid, but I think people are focussing to much on what, in my opinion, are facts, numbers and presumptions.
Blackmagic might very well have packed 13 stops of dynamic range into their cameras but if that's what you're relaying on as a cinematographer, you're not really doing you're job. It does indeed challenges your knowledge of light and the way you (or rather the camera) sees it, but if you can't adjust to that you should probably find another line of work or admit that you don't have what it takes.
And yes, some people are probably going to argue that the GH2 was "voted" the winner of the Zacuto shoutout and that it was only because of the expensive light gear they had access to, but you'll be surprised how much you can achieve with work lights, fluorescent tubes, gels, baking paper, reflectors, foam core and flags (all of which are very cheap) At least that is my personal experience.
...and hey, then you don't have to worry about carrying tons of batteries and spend thousands on storage.
Coming from a photographic background that makes me think of the most famous (and annoying) quote amongst photographers: "the camera doesn't make the creative decisions" also sometimes heard as "the camera doesn't create the photographer"
