I put online the results of this huge test lead on 9 lenses 8 affected and 1 clean for reference, without problems. About 10 hours of work (setting up the used test protocol, shooting, results compilation, sending it on my site), but now we have a solid information about the real influence of fungus in lenses :

I ran it through Google Translate, and I now am reading an article called: "Mushrooms, the big test"..
"Personally, I'm getting great experience with mushrooms, and know in advance, noting their size, they will have an influence or not."

That's normal, "champignon" in french means both mushrooms (the ones that can be eated) and fungus (the ones that comes with humidity, in lenses)

Yes, I figured it was just lost in translation.
... but when you read about "experiencing mushrooms" or the "influence of mushrooms", it is the hallucinogenic type that came to mind first.
