The Canon EF 100mm f/2.8L Macro IS USM Lens is a notably updated version of Canon's popular 100mm Macro lens. In its latest incarnation, the '100 Macro' joins Canon's esteemed 'L'-series, and as such is held to a higher level of resolving power, overall construction, and weatherproofing. Other improvements found on the EF 100mm f/2.8L include Optical Image Stabilization with up to 4-stops of shake control, and a refined Ultra Sonic Motor (USM) for quicker and quieter auto-focusing with full-time manual override.

Like its predecessor, the Canon EF 100mm f/2.8L allows for a comfortable, shadow-free shooting distance between the front of the lens barrel and the subject with life-size (1:1) magnification. Optional extension tubes increase this magnification for exceptional close-up detail.
