Portability absolutely doesn't "always trump photography", otherwise we would all be using just our cell phones.
Anyway, in my world, "portability of some sort" includes the Phantom. I cancelled my Mavic order on the day they announced the Phantom 4 Pro (to get back on topic).
most people are.. he he
i have a few grands worth of M4/3 bodies and glass.. i also have a rather useful fixed lens 1 inch sensor camera.. sadly since buying the rather useful (no need to carry a bag full of lenses) fixed lens camera.. all my expensive interchangeable lens M4/3 gear is sat in a cupboard unused..
i do draw the line at using a smartphone though.. but do accept that the more expensive smart phones will do all that most folks want from them photographically speaking..
i also have a DJI osmo with just a phone type sensor.. but no way on this planet am i gonna fork out the £1500 quid or so to buy the X5 and turn my osmo into an M4/3 sensor camera..
so okay portability dosnt trump photography entirely but its for sure putting up a good fight.. he he
