Objectivity is an illussion, or should I say an assumption we make that others agree with. Everything is subjective. Read David Eagleman's new book, "Incognito: The Secret Lives of the Brain," to see just how non-objective things actually can be. the scientific comparisons sited assume sharpness, higher micro contrast and flare resistance are all superior measurable traits. Some people think that when all the aberations have been eliminated,, the "personality" of the lens disapears and we are left with "just the facts." The latest issue of LFI compares a number of 50mm lenses, new and old, to determine if the Summicron design needs to be updated. In the process the 50 DR is trounced by everything else based on the criteria I mentioned above. In my own experience, this lens is my favorite 50mm and I use it on film and digital with results that are much better on all counts than Leica's test images. For me it's about the unique way a lens sees liight and the images that are possible thanks to that " personality."
