Sent it for cleaning to be safe. As for the dry cabinet, it's the electronic one i'm referring to. Don't trust silica gels to protect yr gear for over a long period of time.Thanks for all the replies. It is my old cameras that I am checking for fungus on, as they were stored in a dry box that have silica gels not replaced for a very long time. I have a Canon that I am not sure if there is fungus or not. From the viewfinder, it seems a bit cloudy.
