I've never had fungus, how does it happens inside the lens anyway?

I'm curious about this too. I've heard of it...just never understood how it could form.

Fungi needs a cool, dark, moist place for it to grow. When the humidity is higher, lenses make an ideal place for fungi to grow because it's cool and dark and because the glues/epoxies used to bind glass elements, as well as dust, lint, and grease, can provide the nutrients needed for development.

Fungal spores will more easily find their way into lenses than out of them, especially with zooms. I wouldn't worry so much about it spreading to other lenses.

I don't think there is any thing you can do, except send it to Canon and let them replace the effected glass.
The big question I want to know, how do you prevent fungus?

if you're in a humid environment, store them in a dry box - something that will reduce humidity.

Edit: That^

The most effective way to prevent mold is to make sure to keep your lenses in a dry place. Fungi need moisture in order to survive. If you catch mold growth early, you can also control it from getting any worse by exposing the lens to a UV source, such as sunlight or any of the disinfecting uv wands.

Cool, I can just set my lens next to my pythons UV light. : )

Hey, I live in Papua (OK 'nuff said).
Would my air-conditioned office room work just fine for storing my camera stuff? I've been wondering about this for months.

I usually keep the temperature around 22-25*C.

Are you safe if you store your lenses in your home and use a dehumidifier to reduce the humidity or should I purchase a dry box/fridge?
