Most of you are owner/operators who can pick and choose what you do to your own cameras. I would not feel so bad if I had a F55 in a professional world because it is the supported Sony camera to shoot 4K internal. Rental houses and multi cam productions would probably have a lot more of an issue unofficially adding 4k to a F5 because it eliminates Sony's support of the camera. Don't get me wrong, i think this is incredible as you guys do. I just wanted to put in the perspective that a huge percent of sony's F55 and F5 clients are not the owner/operators who are represented here, they are large companies with insurance and legal departments and 12K for the official Sony 4k is probably still worthwhile.
