What other macro lenses?

IMO your wide open image is sharp.

I have used 100mm USM macro (non-L) lens and I noticed that full aperture is quite far from sharp.

From my experience with other brands the macro lens has always been really sharp from wide open. Is the Canon 100mm macro exception?

When stopped down to f/4 or smaller aperture, the result is fine.

Here's example crops from center. Focused using live view. f/2.8 and f/4.
