Raven - Light reflection spots from Sensor?

[Moritz Zimmermann]

Hey guys,

I got my Raven just a week ago and have been playing around with it. One thing I noticed is that when I point the camera, regardless of the lens, in a certain angle almost pointed directly into the sun, I get these weird orange reflection spots (see image below). Maybe since this is my first Raven/Dragon sensor camera, I might be too new to all this but can someone explain where these spots come from and how I can prevent them (ND filters?)? When I remove a lens from the camera and shine a light directly onto the sensor, the same visual spot-pattern is visible on the sensor (same for my Sony A7sii but I never got this reflection on a recording).

Thanks to anyone in advance, who´s able to explain this briefly and help me find a way to prevent this from happening.

yes using ND filters will get rid of those red dots.
They typically appear when shooting toward the sun at a closed aperture (± f/11 and below)... so adding ND will force you to open the lens more and they should disappear altogether...

Awesome, thanks. Mikael to the rescue as always.

It's from the OLPF...
Sony A7 Cameras don't have one at least some of them, this makes them more likely to induce moire.
Red's usually don't experience moire but there is always a trade off...
Strong backlight looks mostly better anyways wider open...
Depending on Scenario Matt Box with barn doors can reduce it as well
