An exceptionally fast medium telephoto prime, the EF 200mm f/2L IS USM is a Canon L-series lens that is ideal for portraiture as well as indoor sports shooting or other low-light, fast-motion applications. The large f/2 maximum aperture benefits working in difficult lighting and also afford extensive control over depth of field for isolating subject matter using selective focus. Equally impressive, the optical design incorporates ultra-low dispersion glass and fluorite elements to significantly reduce color fringing and chromatic aberrations for high clarity. Additionally, Super Spectra coatings have been applied to suppress lens flare and ghosting for high contrast and color neutrality when working in harsh lighting.
