It doesn’t come better than the Zeiss 21mm at f5.6 centre frame: bottomless resolution and beautiful rendering. The L has finally shaped up but it’s nowhere near the Contax.

The entire frame is just perfectly drawn by the Distagon at f5.6, barring the wobbly lines . . .

. . . like these. On reflection I’ve called this one a draw: the Canon resolves the mesh detail more accurately but the Zeiss has stronger microcontrast and maintains its performance just a few pixels further into the corner than the L.
