From f/4, the lens performs well at the centre with the aperture set wide, although there it softens towards the edges. From f/8 onwards the resolution is fairly consistent across the frame and with the legendary contrast and colour rendition of L class lenses it produces pleasing results that cannot really be criticized.

If your goal is the ultimate nature macro photos, there is probably not a better choice than the Canon EF 180mm f/3.5 L USM Macro Lens. If you are looking for a great general purpose lens that also does 1:1 macro, consider the much less expensive Canon EF 100mm f/2.8 Macro lens. It focuses much faster, has similar image sharpness and comes in a better portrait and general use focal length.
