I recently purchased a DJi Mavic Pro and during the first couple of test flights on the same day I captured what looks like internal reflections from the camera.
You'll have to view 1080p to see the issue I'm concerned about clearly.
There are donut shaped circles and vertical arked banding. The place to look is the the shaded trees on the left side of the video and focus on the foreground of the video in front of the trees.
The grey dot on the trail is a runner I covered up for privacy reasons.
Looks like flare to me, which you'll get when the camera points in the direction the sun. It can be made worse by flying with the bubble protector in-place.
Falcon, I am sorry to tell that when I attempted to watch the video it is said deleted. Could you please upload the original footage from the SD card to Dropbox so I can check?
