This improved version of an older, and hugely popular lens provides increased speed, performance and optical quality. The EF 70-200mm f/2.8L IS USM lens is ideal for professional and advanced amateur photographers who are shooting sports, wildlife and nature. Its minimum focusing distance of 1.2m/3.9' at all zoom settings is great for photographing in smaller places when trying to get closer to the subject.
This lens features one fluorite and five UD elements for maximum optical quality and reduced chromatic aberration, optical image stabilization that allows for shooting at slower shutter speeds, and dust- and moisture-resistant design for shooting in challenging environments.

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.
