Help! I have ...fungus!!

[ricktas]

I know it's been a while since this thread was last used, but it was either this or start a new thread.

I was cleaning off the lens I use for macro work today, and noticed a little patch of something when I looked through the lens. It's inside the lens as cleaning the external surfaces didn't get rid of it. It's not much at the moment, just a couple of small circles which are mostly clear but give the impression there is something there.

First off, is this likely to be the first signs of fungus. Second as it is inside the lens can I disassemble the lens and clean it off?

Any help gratefully received.

Hard to know without seeing it. Fungus does appear inside the lens, on the internal elements, but without sighting your lens, it is hard to say if you have fungus. It tends to look like spider webs, like long thin lines.. sort of like mould. Hard to describe. If you type 'lens fungus' into google and then click the 'images' tab, you can see heaps of examples.

Thanks for the response, I had another look today and it doesn't look like the images I've seen on the web. Instead of spider webs or worms (spaghetti?) this is almost like circles in the middle of the glass.

I'll keep an eye on it and see if anything....develops!
