I'm not into MTF charts but what has always shown up on the film with Leica glass, over the years, has "looked like" better contrast, better edge, more shadow detail. Does anyone quantify these "appearances" with numbers? Is it possible?>> That's what intrigues me. If these things are not quantifiable, then how could lenses with the aforementioned distinctions be designed and manufactured? Surely there must be some "formula" to get that look, and it so, why can't other makers duplicate them? By this time, there can hardly be any secrets in the industry. Can anyway shed some light on this arcana of lensistry, please? Allen Zak
