I was excited for 5 mins before I used a flash light to inspect the new 70-200 f2.8 is II I just received. Couple white particles/dusts sit on different internal elements and moving along with the element when I turned the zoom ring. They are pretty good size and obviously noticable which I think it is not acceptable for a $2000 new lens with internal zoom sys. Just wondering how offen guys receive a new lens with a similar internal dust issue. I found my recent purchased 100mm F2.8 IS Macro also has dust inside but they are pretty tiny and I can live with that. Canon ever advertised their dust-free production line in a video last year but I think they didn't do a good job this time.
Requested an exchange with the retailer. I have been told retailer cannot inspect lenses prior to shipping under the terms of their supplier agreements.
