I managed to capture many very good images with the Mavic 3 pro's long tele, but the new one is definitely improved.
In what ways is the Mavic 3 main camera better than the new camera that you've not been able to try yet?
You've said that...
If you look at the screenshots of the JPEGs I uploaded, the 100MP image has far fewer visible artifacts than the 25MP version. And of course tons more detail, proven by making it possible to read text where the 25MP image is too blurry.
