I have a red light reflection on the windscreen which could be from the camera as it looks red when you look closely into the lens. When in operation it moves across the screen in sunlight. When not in the sun it's fine.It makes no difference with the A119 CPL filter or not.There are no other instruments near it. Any suggestions appreciated.
Can you share the video, this maybe the lens glare, exist in most of lens, but every lens have different glare.
