Originally posted by dcshooter UV light really does nothing. As long as the fungus is not in a damp dark place, the fungus is already dead, and the spores are everywhere in the environment, so trying to "kill" it is kinda pointless.
+1 and thank you for posting that. If I have to read another "kill it, kill it with UV" post I think I'll barf.
Ordinarily I would pass on any lens with fungus, just because you would need to have it cleaned. However, this lens is not all that common so I might give it a shot. But calculate the cost of a cleaning into the price. And be aware that it is possible (not certain) that the fungus has etched the glass or coatings which is not economically repairable. Still it is around the edges so it might be OK.
I would tell the seller you are interested but need to get it cleaned and see how much they will reduce the price.

Yeah, be careful it will grow out of the lens, across your bag and into all your other lenses. When you open your bag it will be filled with white tendrils of fungus waiting to grab you and pull you in for digestion. LOL,
