Nothing I have specifically states what type of coating any of lenses have. The only reference in the latest M brochure 910716 is: "Procedures that can be extremely complex are used to grind, polish, center and coat individual lens elements" So Leica clearly does not make a big deal about multicoating like many of the Japanese manufacturers... But the older M-6 910613 brochure mentions: "Special Leica multiple coating guarentees exceptional freedom from flare, while ultraviolet light is screened to such an extent that UVa filters only serve to protect the front lens element". Which brings us back to an interesting question...... Does Leica now suggest that we should use UVa filters to protect our lenses??? (Under fire, mayday mayday head for cover........ Duane)
