I'll agree and then disagree as the camera and sensor are clearly designed more for video than stills. On the Professional, DJI provides the
Sony EXMOR Type 1/2.3 sensor with an effective 12.4 M pixels and a lens with FOV 94° 20 mm (35 mm format equivalent) f/2.8, focus at ∞. The ISO range is excellent at 100-3200 (video) 100-1600 (photo). This is the same sensor SONY uses on their FDR-X1000V series ActionCam:

So for it's design and implementation, it's an
excellent selection for aerial photography, but certainly not a NIKON nor CANON DSLR for stills.

But as it's always been said in general photography, "Good photos aren't dependent on the equipment, but rather the photographer" --
