Spot on DNG images?

[JRP Photography]

I'm seeing a soft spot on the top centre of my DNG images, same place and on every image. Jpegs taken while filming on the same flight have no mark at all?
I2 with X5s.
Any ideas?

Can you show an example?

I'll post some samples in a couple of days - I'm on a short break at the moment - without my drone unfortunately!!

The RAW anf JPG were of the SAME shot? e.g you were shooting RAW+JPG?

I have the DJI standard 15mm lens.
No the DNG images were taken during the flight, the jpegs were taken while video recording during the same flight.
It looks like a dust spot but I haven't found any dust!
I don't understand why jpegs taken at a similar time during the same flight don't have the mark.

Good question SanCap - I'll have to check - very bright conditions on the day so I expect so!

If the dng files were taken above f11 or higher you might be seeing a dust spec a little clearer than the lower detail on a jpg at f5.6 or f8, I am guessing.
