I'm finding that I can fly without ND filters with minimum stuttering by using one of the Intelligent Flight Modes like Active Track/Trace where it's all software controlled. In Normal Mode it's possible to minimize jittering if you're steady as a rock and can micro-control. I'm not, and it's not a walk in the park for me. This video is ActiveTrack/Trace at 2.7K using a Taco-RC UV filter. 100 ISO, MM, D-Log and I think the Shutter was waaay up there. Practice helps of course. Filmora was used for video editing.
