My concern with the bolex is that feel. For fiction work I'm sure its great and the footage looks amazing but this is an industrial video. they want something very flat and not stylized. The other problem i have is rental availability. I dont know that i will even be able to rent a Bolex because most local rental shops in LA don't carry it. I believe there is only a small handful. And like Kristoerman said i was also under the impression that the Bolex was not a great low light option. From the tests i have seen it works fairly well and if you don't mind a little grain it looks really killer when you push the ISO but im looking for a very seterile industrial look and feel for this video so I'm not sure thats the right answer.
I should also note that I am delivering at 720 or 1080. No need for 4k delivery but 4k in post would be super for all of the reasons we already know, reframing, sharpness etc.
