Subject: [Leica] Colorfoto lens info
From: "David W. Almy" <dalmy@mindspring.com>

Ben,

This excerpted post from no less an authority than Peter K.: "For those
that may have interest below is a listing of Leica lenses that were
review in the german Magazine ColorFoto.  From what I know, this is
considered one of the better magazines and some Leica Engineers agree
with
their findings (or so I am told).  The data is taken with the lens wide
open (with fast lenses that is what you are paying for) and then 2-stops
down both center and off center..."

And, FWIW, regarding the 180s, I recall test results of the 180
Summicron which said that the best aperture was 2.8. 

Hope this helps.
