The EF 100mm f/2.8L Macro IS USM has a true macro magnification ratio of 1:1, meaning the object you are photographing in real life is the same size as on your camera sensor. This versatile lens gives great results in portrait work and handheld movie-making, thanks to its ability to achieve a shallow depth of field with beautiful bokeh, along with built-in Hybrid Image Stabilization and lightweight design.
