Fungus is a living thing so it may spread to other areas. In some cases
"there goes the neighborhood..." if it's been there long enough to eat
through the coating, only replacement of the element will fix it.

| I may as well ask these questions perhaps for the benefit of everyone:
|
| In my questions I'm assuming the ordinary amount of fungus... which is
| typically spiderwebby and affects one or two lens elements.
|
| 1. How significant a problem is fungus? ie. wil it affect any and all
| lenses with time?
|
| 2. How much does it really affect picture quality?
|
| 3. When cleaned how commonly does it reoccur? Sometimes, always, never,
| depends on how you treat them?
|
| 4. Apart from the link on Siddiq's page on fungus.. is there any other
| links or references to the fungus problem?
|
|
| I'd personally like to know so anyone can feel free to email me off list
if
| they wish to or share the answer here.

There's
