A medium telephoto L-series prime, the Canon EF 200mm f/2.8L II USM combines a flexible focal length with a modestly bright maximum aperture to realize a relatively compact and lightweight design well-suited for sports and portraiture applications. Its advanced optical design incorporates a pair of ultra-low dispersion glass elements to greatly reduce color fringing and chromatic aberrations in order to realize notable clarity and color accuracy, and a Super Spectra coating also helps to increase contrast when working in harsh lighting conditions. Benefitting the optics, a ring-type USM is employed, too, to deliver quick and quiet autofocus performance along with full-time manual focus control. Telephoto prime 200mm f/2.8 lens is compatible with full-frame Canon EF-mount DSLRs as well as APS-C models where it will provide a 320mm equivalent focal length. Two ultra-low dispersion elements greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy. 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 ring-type Ultrasonic Motor (USM), along with a rear focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override. 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. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions. Compatible with optional EF 1.4X and EF 2X teleconverters.
