Hello everyone. I recently bought my new r5 and having a really disturbing issue. I am using my r5 with ef lens adapter with my Tamron lenses. While I am recording video, an instant light like flash is occurring and I don't know what causes it. You can see the issue in the video below. Does anyone faced this or have an idea of what can cause it? Thanks.
