All of those lenses with cleaning marks are *old* lenses, made before "hard" coatings were invented. Scratches... that's probably operator error. Use sandpaper, you'll get scratches. Unless someone is "scrubbing" their modern lens every hour of every single day, for years, you'll not get "cleaning" marks on a modern lens. The coating is indeed *hard* and normal cleaning, using care as to what you use (no sandpaper allowed), will never develop cleaning marks. When you see "cleaning marks", think "old" lenses, or really really bad cleaning technique. Levi's are OK, but not the rivets. Jim PS... ever see a Leica technician, or an optical specialist clean a lens. You should call 911 prior to letting either touch your lens. We're talking "scrub-a-dub-dub"!
