there pretty noticeably different. the biggest change is all the modes.... in 1080p you can choose 140 deg fov, 120 deg fov or 90 deg fov and the picture has better color. the fov is like zoom and 90 degree has almost no fisheye. i use it for my head mount for filming myself flying LOS
that's 1080p narrow mode
heres my hero in it's only choice for 1080, super distant. when that heli spooled up and left it was 10' in front of me.
