Footage from RED's 6K Dragon sensor is starting to appear but let's not forget that 5K is actually pretty good!
Here's a case in point. It's a quick sampler of Andy Brandy Casagrande IV and Emma Casagrande's 5K Epic footage of sharks.
Streaming doesn't do this justice but what you an definitely see - as well as feel - is the sheer presence of these ancient creatures.
Kudos to Andy and Emma for holding the camera steady and not swimming as fast as possible in the opposite direction!
