[Leica] Lens testing

["Erwin Puts" <imxputs@knoware.nl>]

It has been noted:
<Yes. Erwin's tests measure a lot of things, but chief among them is
resolving power.>

I am really flabbergasted. Whatever I discuss and measure, resolving power
is not my chief concern and has never been. I have spoken often  of the
misuse and relative value of resolution testing as a parameter of image
qulaity. Maybe I stop reporting on lens tests or I should do a new course in
English, as this conclusion can be extracted from my reports.
