That comparison is highly flawed regarding Image quality - but i 100% stand by his convenience / quality graph
Long time Phantom 3 advanced flyer here:
I was just about to pull the trigger on either a P4 or an Inspire X5
I am kind of like Casey in that i weight getting the shot and convenience / focus on people / story over lugging tons of gear around
(i attempt to achieve this with minimum effort with a weatherproof GH4 / awesome high end M43 lenses / rode video mic pro / 4k / 96/1080p combo that can all be edited (footage organisation and basic cuts) in the field with a 3 year old Macbook Air.
That video comparison looked really soft on the Mavic's part. I think Casey's super go fast jump cut aesthetic (which I really like) led him to miss the focus set up.
There is some talk that you need to tap to focus first (and maybe Casey forgot to do that part) to achieve results like this from a Mavic
(These were shot On Mavic)
I am impressed!
