New lenses like the Leica 3.8x 1.4 zoom for the Lumix LX7 and other
cameras use a new lens coating technology called "Nanocoating"; it has
nothing to do with the previous lens single layer coating and lens multi
layer coating, it is even better than MC according tests; "Leica glow"
would be impossible with this kind of lens:
