This should apparently result in lesser “out of camera” contrast, which in turn should give good dynamic contrast and richer shadows in black and white photography. In other words, this lens is made for black and white photography.
This lens does not have very good control of light and colors! The perfection of modern Leica lenses is exactly that they can isolate light and shadow with no overlap or overflow, that it can isolate each Red, Green and Blue light ray very precise so you obtain very accurate colors, very good shadow details, high contrast and a minimum of lens flare - and even small light rays from strong backlights won't be overflowing what must be shadows!
