Honestly the Mavic Air still photos are pretty average - it's a 12MP 1/2.3" sensor and even at base ISO you're going to see a noise. Basically the same sensor in a smartphone or cheap point & shoot camera. You definitely need to manage your expectations there. The 1" sensors like the Phantom 4 Pro and Mavic 2 Pro offer enormously better still image quality.
Also try not to pixel peep everything at 100%, as things you see there will never impact a print or web photo.
What about the quality on mavic pro? Any better thn Mavic Air?
