Today I picked up the 77mm after ~2 months on the shelf and noticed fogginess when I looked through the viewfinder. When I took out the lens to examine it, after cleaning the outer elements, one of the middle elements is fogged up. I took a picture of the fog below.
Then I noticed on a
different element lots of tiny dots. None of my other lenses have anything similar. A picture of the dots is below. Is that fungus? They are simply dots, and they look nothing like the fungus photos I've seen. They're also extremely small and the light has to shine just right to make them visible.
Anyone faced a similar problem before? It's the end of winter here in the southern hemisphere but I keep my lenses on an open, ventilated, lit shelf. It did rain a lot the previous weeks though.
Thanks for any help.
