Hi,
I did some searching, but found no really illuminating answer:
I just got an 8/165 SA, and was happy as can be - until I held it against the light. The surface of the front lens - that looked absolutely O.K. on first view - was sort of matte, sometimes a little blue or green colored. Upon closer inspection I saw, that the complete front lens showed microscratches in coincidal distribution. Depending on the viewing angle the surface seemed absolute normal or looked like a frozen sea after days of ice-skating.
You may call me picky, but I am afraid that this amount of "cleaning marks" has an impact on contrast and sharpness, even if I take photos using a shade/compendium to prevent direct light from the sides.
What do you think about it?
Regards
Michael
