It is possible that the fungus has etched the lens, and cleaning won't remove the etching. Think carefully about whether you should keep it.

 I'm constantly buying and selling lenses...  though I'm at the point where that may  slow down... so I'll have to be careful about fungus  moving forward.
Upgrade  path.->means the former was sold for the latter.

I almost purchased a used 300mm f4L that had a hell lot of fungus in it. Luckily, I had a chance to check the lens before I handed over the cash.

I don't buy on ebay anymore because my earlier copy of 50mm f/1.4 came in bad shape and they did nothing to sort out matters.

Anyhow, I live in a humid environment where it rains for more than 7 months n a year. I have got a dry cabinet for my gear. No problems till this day  :)

Hmm, anyone have a link to that "spider-webbing" ? That just sounds like what I saw in my 200...

Many types of advanced fungus have a stringy spiderwebish type look and is a certain differentiator between bad dust and fungus.

Too often we lose sight of the fact that photography is about capturing light, if we have the ability to take control of that light then we grow exponentially as photographers. More often than not the image is not about lens speed, sensor size, MP's or AF, it is about the light.

Wanted to report back that the seller worked with me to accept the lens back and issue a refund.  What a relief!!! Glad Ebay has great customer support and buyer protection otherwise I am not sure I would have succeeded in getting my money back.

Now it's time to save a little more and just buy a brand new 300 2.8 II

Thanks for all of the information and opinions!

Cheers!!!

Thanks ! That is def not what I see on the 200, it's like it's around the edges so that the whole element is displaying some weird pattern along the edges.
