Really. We are comparing two pretty terrific lenses and and let's assume 
an only moderately terrific sensor. The Canon 100 macro is tack sharp. 
If there *are* any complaints regarding the Canon I assume these are 
such that only a very high resolution sensor would be able to notice. 
Leica lenses tend to have higher contrast, and even if in a head to head 
on the same camera the APO Macro has a noticibly higher contrast (in RAW 
mode), after Photoshop where global and local contrast can be adjusted, 
you'd really be hard pressed to tell the difference. Also realize that 
most real world macro pictures have the object of interest in the 
center. Of course that's just my prediction :-) I am willing to place 
$$$ on the fact that after I get done with Photoshop on similar photos 
from both lenses you'd not be able to reliably tell which is which.
