The EF 100mm f/2.8 Macro USM from Canon mixes a comfortable short telephoto focal length with a short working distance. As a macro lens, first and foremost, this lens affords a life-size, 1:1 maximum magnification along with a 1' minimum focusing distance, and the 100mm focal length is also well-suited for portraiture and other mid-length subjects. Benefitting image quality, one ultra-low dispersion element is featured, which limits color fringing and chromatic aberrations for high clarity, and a Super Spectra coating is also applied to suppress flare and ghosting for improved contrast. Short telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 160mm equivalent focal length. Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. A three-group floating elements system along with an internal focusing design helps to maintain consistent image quality throughout the focusing range. Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
