Canon EF 100mm f/2.8 Macro USM

The Canon EF 100mm F2.8 Macro USM is a medium telephoto macro lens for Canon's full-frame and APS-C DSLRs. Maximum reproduction of 1:1 is achieved at a relatively long working distance of approximately 6 inches, and a ring-type USM focus motor provides fast and silent AF with full-time manual focusing. Optical construction comprises 12 elements in eight groups, and image quality is excellent. This high-performance macro has been one of dpreview.com's standard studio lenses for many years.
