if cost is a major concern, pretty obviously the Air3S is quite a bit cheaper option
I don't have the Air3....I have a Mavic 3. My hunch is that the Mavic 3 Pro is superior to the Air3S. The 4/3 inch sensor vs the 1 inch sensor is part of that...
The short tele lens of the Mavic 3 pro is the same as the one on the Air 3S
Smaller sensors can't produce results as good as larger sensors do.
The long tele of the Mavic 3 pro is surprisingly good in good light.
In lower light levels, not so...
