Charles, Actually, I strongly feel that the Leica lenses are fully up to the task of being used on a digital body as well as a film body. All we have to do, is look at the pics posted on our site, no matter what digital body that is used with the Leica glass. Leica lenses are almost optimized for evenness of illumination across the entire image field when wide open, and improve only slightly when stopped down, as do Nikon's ED lenses, or Canon's "L" series. This is just my personal observations from shooting just about everything from about 1960 on. Art
