The Canon EF100mm f/2.8L Macro IS USM lens is the first medium-telephoto macro lens to incorporate Hybrid IS, a new Image Stabilizer technology that optimally compensates for both angle camera shake and shift camera shake. In addition to a dust- and moisture-proof structure for shooting even under severe conditions, the new lens also offers a nine-blade circular aperture for beautiful, out-of-focus blurring effects for points of light, even during close-range shooting.

While the EF100mm f/2.8L Macro IS USM features an approximate 4-shutter speed steps correction capability*1 during normal shooting, it also realizes an approximate 3-shutter speed steps when shooting at 0.5x magnification and two steps at 1x. when shooting close-range*2 . Additionally, the incorporation of a UD lens element reduces chromatic aberrations in the macro range to an absolute minimum, enabling photographic expression with high levels of resolution and contrast befitting an L-series lens.

*1 Based on a shutter speed of “1/focal length” seconds, considered the limit for hand-held photography with an EF lens without image stabilization
*2 Compared to normal shooting, a shutter speed approximately 1–2 steps faster is required to prevent camera shake in close-range shooting
