The problem with the scientific BAS test, is that they were not afraid to give 110/100 (yes) to the Leica APO SUMMICRON 2/180mm. More than the maximum. Really scientific! And they gave the same result (100/100) to the APO-MACRO-ELMARIT 2,8/100m without and WITH the APO-Extender 2X. Wow! I own the 100/2,8 and the APO-2X, and together they are outstanding, but I don't think that the quality is equal on a scientific base. Now that we have the APO SUMMICRON-M 2/90mm, which according to Leica is even better, if not the best Leica lens ever made, how much will they give? 150/100 ?? ;-) Lucien
