Because Sony helped finance the movie and made it part of the contract for them to use the a7S II to use as a marketing tool like they're doing here to make people believe they can make a hollywood film with their camera.

I also agree most of MZed's people are not renowned working DP they're simply videographers. Shane is the exception and I think he has given a lot to the community. I like your world class DP list BTW.
