At one time Leica was providing this at a nominal charge and I am certain Leica owners would enjoy reading it. This may be very old news to the LUG but it does contain a lot of good information about the lenses and they are explained through MTF graphs regarding sharpness and brilliance. The method of testing is also explained. The only drawback is the publication does not include ALL of the APO and ASPH lenses that are on the market. The questioning of Mr. Puts credentials may have been brought on by persons who have read the BAS report and wanted to compare the two methods of testing. There is a copyright note on the publication; otherwise, I would be happy to scan and convert the report to a PDF for those who are interested.
