There has been extreme excitement over the last month for both the GoPro Karma Drone and the DJI Mavic Pro being the first truly portable and collapsible drones that offer professional features and a quality camera. However when we focus on the video quality it is clear that by several measures the Mavic Pro seems to be a step down compared to the DJI Phantom 4 and here lies the main issue between these two competing platforms.
GoPro has not been a quality champ ever since the DJI Phantom 3 came out. The Hero Camera with much more wide angle distortion and less sharpness was a letdown by being pretty much the same since the last refresh of the GoPro Hero 3+ several years ago. The GoPro way has been footprint reduction and feature addition instead of image quality hikes.
