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.
