Is that a problem when you are shooting a full frame SLR?
That's a question for the technical people at DJI, but my guess is there's a good reason for it.
Huh? You will get less distortion on the 28mm vs the 24mm. Just fly a tiny bit further if you want the 24mm “equivalent”. That’s a funny post to try to justify the M3…
