Just bought a D700 and a 24-70mm. lens. The 24-70 isn't here yet but my roommate has an 80-200mm. lens that he wants to sell. I was inspecting it and discovered that there is a little bit of dust and a single fuzz right in the middle of the element (when I close the aperture down all the way, it's still in view). I cleaned the outside element with Eclipse2 and some swabs but it's obvious that it's all on the inside. Is there any easy fix for it? I think it's behind the first element because it's behind the diaphragm so it's not like it's in the middle of the whole lens. I love this lens and would love to buy it from him but if it's not easy enough to fix I'll seek elsewhere. Thank you for ANY help at all.
