Camera lenses are highly suceptible of suffering fungus attack. I will put these ones in first place…
Old camera bellows may suffer of cracking. In some cases I will leave them in a middle point between closed and fully opened. That depends in their actual shape and the HR in the place, even if the loss of plasticians is not something a high HR can give them back and the elasticity is loss forever in most cases (luckily is one of the camera parts more easy to restore with good ethics results).
