COG3+ Slightly blurred now?

[AH-1G]

Several weeks ago I took some aerials at a commercial business and noticed the clarity was not there. Today I had the same issue.
Even before my mishap last week the clarity was blurred.
I have two examples, 1st is McDonald's many weeks ago( RAW File),
and today out in the boat (Raw File)
These pics come straight off the video's
I know I adjusted something but not sure what?
I always manually adjust the camera ISO and shutter speed.
Boat pic settings are @ ISO 100, 200 shutter with filter.
I'm thinking my shutter was to high, I maybe should have gone to 100 or 125?
I've been using the ND8 filter for over a year for all my video and photos.

Not sure how to fix that. You can try and clean the lenses. Or try and keep the drone more steady.

Lens always cleaned and no wind. I was just hovering, also I've been in winds up to 25 mph with no distortion.

I'm not seeing much blurring in the first one, but in the second it is much more severe.
What FPS were you recording video at ?

@AeroJ Hey thanks Aero for mentioning that, for some reason it was changed (hmmm, must have been when I was piddling around)
so I beefed it back up to the 3840 x2160 area.
Do any of you folks use the 4000+ frame rate?
