Hi,

My canon 80-200 F2.8L getting fungus on middle
element.
Do you guys think I can use UV lamp (Taken out from
water sterilization system) to kill the fungus and stop
its growth ?
I knew that the fungus will not disappear but hope
it will
not be worse.



It can't hurt to try, but I think the glass will absorb most of the UV before it can get to the fungus.

How much UV does the lens glass absorb with no UV filter?
