I have recently bought a lens, and it has a lot of fungus in it. I mean A LOT! :D I only bought it very cheaply, so I dont really mind, but I am thinking about how to get rid of it, or at least to kill it in order to stop it spreading. I have tried a few methods:

- My mum is a dentist and she got me a very powerful UV light, which is used to kill bacteria in a surgery.

- I have left the lens for hours under a very hot light bulb, which in theory should have toasted the fungus. (Left it over night and the glass was RED hot when I finished with it, so I hoped it would have killed the bacteria)

I don't know how to fight it any further. To be honest, I cant see it spreading, but I don't know if my treatment has helped or not.

Guys any ideas or suggestions? :geek:
 
I personally would not use the lens and get rid of it, I would be worried about the risk of the fungus spreading to my other kit.
 
Fungus in a lens is a no-no for me, its the one thing I refuse to accept.

Got this "excellent condition" lens on Ebay the other day... :gag:

Personally I'd bin 'em.

Had a right old ding-done battle with the seller over that one... !!
 
Can fungus spread to a body? because I have heard that they dont go into digital bodies, since they have nothing to feed on. (In the lens they feed on the glue used to glue the glass)

The spores could get in the body then be transfered to other lenses or if it is kept in the same bag/draw them spores can spread, to me unless the lens is ultra rare it just is not worth the risk, inactual fact even if the lens was rare it still is not worth the risk.


To elaberate on the spores getting into the camera body, the action of zooming the lens can suck or blow the spores around and the mirror moving can also blow the spores around.
 
the idea of fungus in a lens is just mental, who'd have thought it
 
I'm surprised that problems with fungus are cropping up in the UK as I've always associated it with more humid climates. But it's about the third thread I've seen on forums recently.

As far as I know you can kill the fungus with UV light, but it could well have eaten into the lens coatings if not the glass itself. Personally I wouldn't even consider buying a lens with fungus. But as you've already got one you may as well try it out and see if there's any degradation in IQ. Providing you've actually killed it I'd guess there's no danger of it spreading to anything else.

The UK is one of the most humid countries in Europe, so I would have to disagree with you on that one.

But thanks for the comments, and I will provide more UV treatment for the lens when I can.

Still looking for more suggestions :D
