Fungus on Lenses

[Paul_O]

Does anybody know if it's an expensive or worthwhile process to remove fungus from inside lenses? There's an 80-200 f2.8L lens I'm interested in on Ebay but it has fungus and deending on pricing may be worthwhile snapping it up then investing some money in it.

Are there L lenses in black or do they only can be bought in white?
The lens you are refering to is a black L lens, so i wonder if L lenses can be obtained in white to.

Sorry, made a mistake. Read as:

Some are black, some are white. None are available in a choice of colours.

1. Call your local Canon dealer see whether they have the lenses parts or not. If not don't bother.

2. You won't know how long does those fungus has on the lens elements. Fungus will eat away the coating. Which end up need to replace the lenses, So don't bother.

Before I would sell a Canon L lens on eBay for a paltry price, I would very thoroughly inquire at Canon how much it cost to repair it.

Most likely it is not really worthwile to have it repaired.

Still, if the lens gives sharp pictures, then you might go for it. For the current price

I remember seeing a NOINK 400/2.8 lens (price new: ~US$ 10,000) with fungus going below $ 1,000 on eBay.

I think I read somewhere that the fungus can be killed with radiation, but maybe you ask an expert.

And as to the colour ... the 80-200 (old lens) was still black, the new one (70-200) is only available in white.

Hmmm, sounds like it's hardly worth the trouble but thanks for the replies.

the 80-200 L is a very good lens - In my opinion, its worth contacting Canon to see if the fungus problem can be repaired and for how much. Its worth a quick inquiry IMHO.

Firing ultraviolet light into the lens can kill it, but the damage may already be done.

Last year I had bought a second hand EF28-70 f2.8L USM lens with fungus. It was so cheap that I could't resist to own L lens. Fortunately fungus was mostly on edges and on my D60 with it's crop factor, it was outside picture area. But fungus makes me nervous, so I took lens to local (non authorized) camera service. Technitian explained to that in case that fungus is not start to "eat" into glass it can be cleaned without any problem. So I accepted risk and left lens in shop. After a week when I collected lens it was spotless clean and absolutelly no traces of fungus. I was very happy to pay some 80€ bill. After some six months now there are still no traces of fungus inside the lens.

"i had another look at the lens under sunlight and it looks as if more of the elemets are affected looks more like 5 or 6 elemts have fungus not 3 elements"
dont think i would buy it. seem like it would be to costy

[Andy_T]

Well,

if you just want to kill the fungus and live with the damage done to the coating so far, then it would not matter how many elements have the fungus now.

If you want to replace the lenses, then it will be costly.
