This video of a damaged GoPro sensor is to show you how you should definitely take this issue seriously.
We all know how expensive cameras can be, and personally I don’t know a single photographer who would deliberately do anything to harm their gear. I’m always trying to do everything I can to keep my cameras and lenses in good condition – a damage like this would drive me insane. Here is a screenshot from the video below, showing you the big streak in the middle of the frame. On the video you can see how it got there.
