Just to add to the confusion...some wide-angle lenses that can focus very closely, such as the TS-E 24 II and the 8-15 fisheye, can make for much more interesting "macro" lenses than a true, dedicated macro lens. They let you get super-close to your subject for an interesting perspective and generally do a great job at including enough of the surroundings to put it in context.
The Sigma 20mm f/1.8 is king at this although it has a macro ratio of 1:4
Edit: due to its MFD of 0.2 m.
