At first glance, the EF 100mm f/2.8L Macro IS USM may seem exactly like the EF 100mm f/2.8 Macro USM lens. It has the same fast aperture and autofocus that lets you close in on the entire flower while keeping the finer details vibrant. But this L-series lens was built to meet the professionals’ standards: image quality that exhibits superb resolution, excellent contrast and minimal chromatic aberration. It also has a dust- and drip-proof design, protecting it from fluctuating outdoor conditions. The hybrid image stabilization system detects two types of camera shake to improve the likelihood of capturing a stunning Macro photo.
