Re: Help! What's this in my lens?!

I don't like the looks of that and it's not normal. It might be fungus which is unusual on relatively modern lenses, but maybe some sort of vapor or oil has condensed in there and left residue. I'd either sell it "as is" at a discount, or get it cleaned. Good luck!
