From the Canon USA YouTube Channel:
"Macro photography is all about photographing objects that are really close to the lens. Macro lenses not only let you close-in on a subject, but also allow you to zoom in on a subject that you cannot get close to. Photographer and educator Matt Kloskowski gives some tips on the best way to capture images that are up to 5 times normal size with Canon's MPE-65mm."
