Hey guys. I dropped one of my lenses for my medium format camera in mud. It wasn't too bad, just a few splatters of dirt, and water on the lens. I washed the mud off the lens lightly in the sink, but I noticed that an internal lens has some fogish look. It's very faint, but I saw right away that it did have water that made it inside the lens onto the piece of glass. It looks like it might have dried, and the foggish look is left. What are the chances that this is fungus, or that the internal lens just still has some moisture to dry off?
