How's this for annoying - just opened my newly delivered 300 2.8L IS and 70-200 2.8L IS and BOTH have small defects
The 300 has a smallish dust globule under the front glass and a largish mark (a smudge of some sort?) under the rear glass. The 70-200 has again a largish dust spot under the front glass right in the middle! I've tried cleaning and gently tapping to see if all would move or fall away but no luck! So they're both going back. I know that none of the defects will effect final image quality but when I'm paying out this much cash I want things perfect! Oh well at least the 17-40 I also ordered was ok
