John,
   I keep all my lenses sitting on a shelf in a closet. They have their
lens caps on but are unboxed. The key component however is that the house
is always air-conditioned or heated. The interior humidity is always about
30-35%. I have never had fungus in a lens that I have been able to detect.
I did have a hazed element in a 65-200 Zuiko zoom but no fungus. I still
have a Zuiko 75-150, f4 zoom that I purchased new in 1977. Clean as a
whistle. If AC is not an option, I recommend storing unboxed lenses in a
heated (piano heater works well) wooden cabinet with a can of desiccant.
