Explanation from Sigma

Although telephoto zoom lensescan be used closer to the objectthan fixed focal length telephotolenses, there is still a minimumshooting distance. SIGMA hasmade this minimum distance smaller and developed the zoom MACRO lensfor taking close-up photographs of the same quality as those taken with aregular MACRO lens, while maintaining the performance specific to anAPO lens. Rather than carrying around the cumbersome accessoriesrequired for close-up work, the photographer can now take photographs ata magnification of 1:2 (one halflifesize) using a telephoto lens, byquickly shifting from the normalsetting to the full macro setting.
