Interesting. The marks in my lens are radial, ie they go around the lens in a circular pattern and cover basically the whole area of the element. Is this typical of your experience? I wondered if it was cemented elements coming apart but it looks too far into the lens to be the two- element group. It would be near-impossible for me to get a photo of the marks as I have to look directly into the lens with the sun right behind me. Cheers, - Dave http://www.digistar.com/~dmann/
