What I found out about the Mavic pro is that even at minmum ISO, there is a bit of noise on the DNGs, so it is really better to stick to a low detector sensitivity (you don’t want the noise to be taken as features).
I don’t remember about the ISO setting on the MAVIC, but yes, I would definitely stick to the lowest ISO. Aperture is fixed, if I remember well… And stabilization is doing a great job at slow shutter speeds.
