[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]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. David W.
