Cameras are to be used, not stored unless you are a collector. Collectors don't bring around their cameras all the time in their bags unless they are training themselves by weight-lifting. When cameras are being often "exercised", fungus dun grow. If you are bringing your cameras overseas for trips, as long as you are using them daily, they dun grow fungus. Well at least that works for me for years and I've never had a lens with fungus as long as I use them. But if you store a lens in a dry cabinet not used for years, fungus wont grow but your lens might still get FOGGED. That's due to chemicals/glue in between the lens elements causing a chemical reaction within because the lens has not been moved("exercised") for too long a time. So, bottomline is sell those stuff you dont use and let those who appreciate them get a chance to use them OR lend your unused lenses to buddies for them to "exercise" them for you every now and then. See? Lenses are not meant for museums but meant for real shooting photographers!
