Just noticed that I have something inside my R5 viewfinder. Any opinions on what this is? (Ignore the countless micro scratches on the outside and dust around the edges, yeesh!) I guess I'm mainly looking for the reassurance to not freak out about it. Even if it is fungus, from what I have read about fungus in camera equipment, it can't really "spread" between cameras and lenses, but rather it's pretty much present everywhere at all times, and it's just waiting for a good environment (moist) to be able to actually take hold and grow? Thanks.
