Paul,

You should send this information directly to Leica AG (Solms, Germany) as
they are publishing information to the contrary. I am sure that they would
like to know the error in their ways.

Last paragraph, page 55, document #920 083

"Leica lenses from 1965 onward absorb UV through the use of certain types
of glass and above all through a certain method of cementing the lenses. A
UV filter is unnecessary. Even at high altitudes, the UV filter has no
effect."
