>>4256511From my understanding there are different types of fungus and some types are harder to remove. I believe that lenses that have been stored in wet climates are harder to fix. On top of that you have the complexity of the lens to deal with. I have cleaned a few lenses and had no problems, but i live up north.
>>4256554>it's not fungus, it's mould, and there's a high chance of getting mould on your sensor.That is just stupid. It is not the back elements that are exposed to fungus growth.
