I have seen two lens infected with fungus in funan mall. One being a new lens in a camera shop and the other being a lens stored by the user in a non-camera related shop. Both in funan, where we buy our camera stuff. Does it mean that even though air-con places are lower in humidity, chance of fungus is still high? If I am getting a "not so popular speciality lens" that has been sitting in the shops for months or years, will the chance of fungus be a lot higher?
