Improving upon one of the most celebrated lenses in the Canon EF line is no easy feat, but Canon has done just that. The all-new EF 70-200mm f/2.8L IS II USM increases the speed, performance and optical quality of the EF 70-200 f/2.8L IS USM while maintaining all of the characteristics that have made it a legend for professionals and advanced amateurs alike. The EF 70-200mm f/2.8L IS II USM features one fluorite and five UD elements for increased optical quality and reduced chromatic aberration. It has a minimum focusing distance of 1.2m/3.9 ft. at all zoom settings, which is useful for photographers in smaller spaces trying to get closer to a subject. It features a next-generation Optical Image Stabilizer, providing up to 4 stops of correction at all focal lengths. And as with all L-series lenses, the EF 70-200mm f/2.8L IS II USM is dust- and moisture-resistant and designed for use in the challenging environments typical of rigorous professional use.
