I agree with Patrick, I seem to find the 12mp during low to be better.
Off topic a bit, I take a lot of long exposure photos with a ND1000 or ND2000.
The 48mp can only take shots upto 3 or 4 sec. But the 12mp can go upto 8sec. Yes these drones...
However when watching the video on a 4K screen I still notice a huge gap in image quality between the 28 mm and the 70 /168 mm lenses as opposed to what people said
