I still have my Graflex Xl ( purchased in the late 1960'S ) have no humidity issues.
Have 2 lens 80 MM Zeiss Planar & 180mm Rhodenstock Rotelar - no fungus issues!
Also Have a Pentax Me Super from the 1980's - no issue.
Not worried about my Pentax K-1 MarkII since it is sealed better than my two other cameras.
Perhaps you don't live or use your gear often in an area with high humidity and fungal spores.
