Just spied your Iceland gallery.... WOW!! you have some spectacular shots there. Love those natural patterns, always on the lookout for those now I have a drone (albeit a very small one!)
My friend and I have 6 days of bliss every year and go on a winter photography trip in NZ. Back in 2017 (when that Ohau shot was taken) we struck the biggest fall of snow we have experienced in a long time (by NZ standards). The closer you got to Tekapo the heavier it got, was a photographers paradise. Shots from that trip can be found lower down on this page...

I totally agree about DJI not focusing on Drones to make stellar still images, definitely seems more about Video or at least that format can cover up lens flaws more easily. I almost purchased the Autel Lite+ even though the sensor was only one inch just because the optics seemed superior (sharp edge to edge) compared to even the
M3. I would happily pay $500 more for any drone if it would give me optics like I'm used to on my DSLR. As a Fixed Lens it must be possible, there are some pretty sharp, low cost fixed length DSLR optics out there. I used to buy kit zooms and middle of the range lenses for my Olympus but as soon as I got into their pro range 12-100mm and 300mm you just know no matter where you point that lens it's going to provide very clear images.
