Fungal growing in lenses?

[Jack]

I found somewhere that there is a chance that in the lenses can grow some kind of fungal, which i think I've seen such of discussion here on forum.

I would like to ask how this can happen and how can i prevent this?

Thanks

In old ones, more debris accumulates during use, so this happens more often with old ones.

I was starting to worry about my new lenses. Which aren't very old, maybe couple of years, but all dust and water sealed. Can they be affected too?

I read about this in one of the articles on the Internet, I did not come across it myself. You have a very humid climate, which is favorable for the growth of fungi and mold. But in fact, this is a great rarity.

In UK the humidity is very high. I still keep my lenses in their manufacture bags. Idk, is that having some silica can prevent or minimise the risk?

Yes, I just wanted to say that Selikogel or another desiccant will help to avoid this.

Then I might buy some small bags of them, and to put inside each bag with lens. How about cameras, can they be affected as well?

More on electronics in cameras. But boards and others are waterproof for the most part.

So lenses which are water sealed and dust sealed had same risk as old lenses?

My binoculars got full of fungus and i had to throw them away, but none of my lenses so far. However they are all quite new.
I store them in a sealed box with silica in it.

Thanks for your reply Sergey Prokofiev , lovitazoe . So is there any way to prevent that happen to lenses? Does this affect all lenses or just old once ?

I put 2 bags silica gel inside my camera bag. My camera and lenses are water and dust sealed but still can't avoid this problem. Usually if we don't use our camera for too long and just leave it inside the bag or an ordinary storage, the fungal will appear.

From what I know, an airtight storage/dry box, silica gel, and UV light will help the camera safe from fungal, Jack. And of course clean the camera after we use and before we store it back.

What kind of box?
