I recently purchased a Canon 80-200 f2.8 L (M. Drainpipe) but immediately noticed upon inspection with a pen flashlight, that there was a lot of spots/specs on one element and the same type spots/specs isolated in the middle part of another element, which was very odd.
The later really concerned me because I thought it possible fungus had begun to grow in the middle and just hadn't had time to spread outward on that particular element. It definitely doesn't seem to simply be dust specs because dust varies in size and they don't simply congregate on one spot of a lens. Anyhow, others on POTN felt it was delamination taking place but either way something isn't right with the lens.
MY INQUIRY IS THIS: I returned the lens to the Seller who stated she took it by a Canon store and had a "technician" look at it who stated there was no delamination, no fungus and that he only saw a "little" dust inside and that such was "normal". The problem is she lives in Florida and there is no Canon Service Center in that state. I was always under the impression you had to ship your gear to one of Canon's Service Centers to have them properly inspect, clean or repair?
So, what type of Canon "technician" could she have had look at it or do you think it was just a Salesman giving an opinion?
Needless to say, she wants me to cover the $20.00 in original shipping for having shipped her perfectly good lens back to her...

Otherwise see the image below of the one element that is completely covered with these specs. It was to difficult to get an image of the element with specs isolated only in the middle. Note: the light flare is just from my flashlight.
