Primarily designed for close-up shooting, the EF 100mm f/2.8L Macro IS USM from Canon is a versatile L-series short telephoto prime that is also well-suited for portraiture and other mid-range subjects. As a macro lens, however, this 100mm offers a life-size, 1:1 maximum magnification and an 11.8″ minimum focusing distance. Complementing close-up shooting, an Image Stabilizer is featured that minimizes camera shake by two stops at full 1:1 magnification or up to four stops at lower magnifications for sharper handheld shooting. Also contributing to smooth and intuitive handling, a ring-type USM and internal focusing design offers quick, quiet, and accurate autofocus performance along with a full-time manual focus override. Concerning its optical assets, one ultra-low dispersion element is featured, to control color fringing and chromatic aberrations, and a Super Spectra coating has been applied to suppress flare and ghosting for improved contrast and color fidelity. Additionally, as an L-series lens, this 100mm f/2.8 is weather-sealed for working in inclement conditions.
