Henning... you are among the few LUGgites that can read and make sense of
MTF charts.

Can you give a quickie review of the MTF charts for the 4 x 21mm lenses?  21
ASPH Elmarit, WATE, Summilux, and Super Elmar.

I have always wondered their relative merits....

 From the MTF graphs the new 21 looks as good as anything ever made at that
focal length, but it's not perfect :-). Still has distortion, the sagittal
and tangential curves don't cover each other, they're not all above 95 at
40lp/mm, and there is significant light falloff. 
When will they ever make a perfect lens??? :-)
