Is this kind of warping normal for a mavic air 2?

I think post #14 is the most relevant.
89.9 degrees seems very close to -90, but IMO would account for the "skew" in the photo, since it is taken from 220 ft away. The picture variance is NOT from drone rotation, and to be from camera/lens distortion is IMO not possible. A double check of this would be to rotate the drone 180 degrees and take the same shot. I'll bet the lines would skew in the opposite side of the field.
I would do two things, retake the same photo after doing a gimbal calibration, and use the cross hair grid on screen and make sure it is pointing dead center to the middle of the field. Do the 180 rotation and shoot again. Hopefully the camera will be at -90 and you will get two perfectly straight-lined photos.
Keep us informed!
Of course, we are assuming, (probably correctly), that the field lines are dead on straight

Thanks. I went back and read the flight data. there were MANY rows of -90.0. I missed it.
But there were also 89.9's.

Can you tell when the shutter was activated in order to lock in what gimbal setting was there?
