Looks like classic case of Schneideritis. Google it.

I also seem to have a 17-40mm which 'caught this disease'!!!

Didn't use my lens for a few months, and moved over very long distances twice in less than two years and last week wanted to use my lens again and was greeted by a bunch of weird white spots in between the front lens group!!! Yikes, didn't look like anything I ever saw before (dust, mould, you name it!).

Posted a question about it here on the forum before I found this one but nobody really knew what the problem could be either...

Any who, what you came up with really seems to nail it!

Thanks!
