It's not the full-frame's corners, but the corners of the cropped field I 
spoke about. And even there the Leica ASPH lenses perform better. On the 
the full frame corners (on film) the difference is logically even bigger. 
And vignetting with wide angles is an issue on the R-D1, too, as many 
reported.
