I faced a similar situation. At first I noticed, looking at the video of the winter forest on the TV screen, where the branches against the background of snow give a good idea of the sharpness. Then I discovered that when shooting a 360 panorama, which is carried out without the possibility of manually adjusting the focus, on the same objects, but in different zones of the matrix, there may be different sharpness even in adjacent frames. See an example under the spoiler. I decided to check it more or less instrumentally at home.
So, we have a flat 4K TV, a prepared line image, we absolutely accurately align the drone’s camera on a perpendicular axis from the center of the frame (there are crosses in the center and reflections in the screen of the front lights just above the camera axis). Recording from the smartphone screen and twisting the manual focus in the sharpness zone selection mode. The result is a complex circular unevenness of the sharpness zone, in my case, also slightly tilted. Unfortunately, with an unregulated aperture, it is better not to get. The ideal plane of sharpness is difficult to achieve, but it exists. And it's not a fact that autofocus always gives an ideal compromise across the entire field of the frame. Keep this in mind. I have been using the drone for more than six months, it is from the first batches, I didn’t notice this in the summer, because. filmed more dynamics. I will use manual focus more often, controlling the area of sharpness. The tests were carried out in a warm room, there is no winter factor. And by the way, in terms of geometric distortion, distortion, the lens is excellent. Here is the focus. Who wants, you can do it yourself. Maybe, of course, I have such a copy, but I think that just the majority, like me in the first months, does not notice this. I did not experiment with other Air2S drones, but, for example, DJI Osmo Pocket does not have this with a smaller matrix.
