I checked the Dennis Laney book, _Leica Lens Practice_ 2nd addition and on page 152 it does discuss it briefly, "Critical exposure measurement is important at full aperture for subjects with uniform brightness to avoid the falling-off in brightness at the corners which is inherent in the design..." Since I don't shoot plain walls or the sky maybe I just haven't seen it in mine. But then what do I know... other than it is the sharpest lens I own.
