A couple of issues still to be resolved. Does the Mavic allow video shooting un interrupted, without losing frames after about 9 min in 4K? The GoPro5 on the Karma, although it splits files, does not lose frames between splits.
A comparative video on YouTube between Phantom 4 and Mavica shows that the images and video from the Mavic are certainly not as sharp as the Phantom4.They are supposed to have the same sensor but not lenses.
The specs on the DJI Mavic page says the Mavic is capable of flying out to 13km but the controller connects out to 7km/US and 4km/Eu and there is a significant difference between the Us and European transmitter power resulting in inferior distance performance of European and Australian units.
Maximum service height 5000m but what about operating height.
I think I need both the Mavica, portability, distance, flight modes, flight time, video streaming but also need the Karma detachable gimbal, waterproof GoPro 5, include grip. I can see a use for both. On a camping trip the Karma has the ability to do ground and aerial footage with stabilisation but the Mavica has the ability to get great shots from a distance to reveal all and is smaller and lighter.
