However, the higher sharpness is delivered at lower contrast levels which in the photographic practice gives less interesting pictures (David Hamilton may disagree). Leica started calculating their lenses in the sixties to deliver maximum contrast, rather than maximum resolution. Also, coatinglayers are chosen in order to enhance contrast and Leica may accept some vignetting if the final result is higher contrast. In my opinion, their design philosophy is absolutely right. I have a collapsible Summicron f 2/50mm which is definitively sharper than their recent Summicon f2/50mm but the Kodachrome slides made with the recent lens come out much nicer due to better contrast transfer (crispier image, more saturated colors). In terms of black-and-white negatives, the difference in contrast between Leitz fifties- and Leica's contemporary lenses is in excess of one photographic paper gradation level.
