The Olympus has distinctively soft micro and macro contrast compared to the Leica and Canon. The 19mm f2.8 just about steals it here again, though.

We’re seeing a pretty level playing field at f11, but still the Leica shines.

If you can afford to stop down this far, the Canon delivers a fair corner. Apart from the last few pixels, the Leica looks pretty good also. The little Zuiko lags.
