factory markings on lens elements?
Guys,
I just purchased a 70-200 f2.8IS and I want to be sure it's ok before the RMA time is up. I noticed under certain angles that there is a miniscule "O" marking on the front lens element, and well as another "O" or possibly a solid "O" (it's so small I can't really make it out) in the glass behind the front element. Is this standard from the factory? the one on the front element looks too perfect to be a defect, but I am not sure about the one in the second piece of glass. Hope somebody can shed some light!
thanks
