Since this has turned into a camera discussion, I'll throw in my 2 cents...
We mostly fly the GH2 or the GH3.
A properly hacked GH2 packs a lot of punch. Detail is good and dynamic range is decent. Since you can crank up the bit rate to nearly ProRes levels, it retains a lot of information without macro blocking and other various compression junk. It's a great little camera for aerial video. As a stills camera, there are much better options available.
The GH3 can do 24p, 30p, or 60p all at 1920x1080. There are plenty of expensive cameras that can't do 60p at 1080 - they're limited to 720. We usually shoot in 24p, but having the option to go to 60p for slow-mo is handy. You can't hack the GH3 yet, but the bit rate is fairly high right out of the box. The dynamic range seems to be slightly higher than the GH2. There is one area where the GH3 suffers - moire. Point it at a brick building from the right distance and it doesn't look so great. So when we have a shoot with a lot of brick buildings, we revert to the GH2. We've used the GH3 on features and TV shows that were shooting Alexa, and with a bit of color-correction it matches pretty well. We've even used it on some productions where the ground work was on an Epic (when the final product is 1080). The GH3 is a pretty good stills camera too.
We just got a Black Magic Pocket Cinema. Initial tests look good. More on that one when I have more to say. It may become our go-to camera for Alexa based projects.
I've flown the FS700 on two shoots. It's a long camera, which can make things tough. I'm not nuts about the image that comes out of that camera. It's a quirky camera too - not the most user friendly. But if you need SLOW motion, it's a good option.
The 5D MkIII for aerials? I've tried it. Not a fan. Just personal preference. I just don't think the video from this cam is all that great for aerials. It lacks detail and has a fair amount of compression. I haven't messed with the ML raw hack, but I know there are some limitations there and you could seriously anger the post production department when you hand over files that they don't have a workflow set up for. It's a great stills camera though. But it is heavy.
The Epic and the Scarlet? I've flown them. They're not the most fun camera to fly because they're heavy. I run a larger battery on the gimbal so that I can power the camera too. And these things can drain a camera battery quick! They're good for high resolution and the picture is gorgeous when handled properly in post. Things can move a little bit slower with this camera unless you bring a PA to help you lug it around. They're expensive, so get some good insurance!
Sony F55 - I'd love to try it. That camera makes a pretty picture and probably has a better menu structure than the Red.
Canon C100 / C300 / C500. I'm hoping to fly a C100 soon. These cameras have a lovely picture and you can strip them down so they'll fit on a gimbal well. The C300 is seriously popular for documentary style shoots - mainly because it has a great picture right out of the camera and it is the low-light king.
I've got plenty more opinions when it comes to ground based shooting, but I'll keep it focused on aerials to stay somewhat on topic.
These statements are only my opinion, I share them to be helpful, and don't mean to offend anyone. And the camera-person is more important than the camera (It's the artist, not the brush).
