The EF 70-200mm f/2.8L IS II USM Lens from Canon improves upon its predecessor, one of the most acclaimed lenses in the Canon EF line, with superior performance, increased speed and optical quality.
This lens construction consists of one fluorite and five ultra-low dispersion optical elements which help deliver the sharpness and reduced aberrations. The IS II Optical Image Stabilizer provides up to 4 stops of correction at all focal lengths and features two modes for stabilization of still objects and while panning to follow moving subjects. An ultrasonic focusing motor provides fast, smooth and silent autofocus action.
This lens has a minimum focusing distance of 3.9′ (1.2 m) at all zoom settings so you can shoot close to your subject even in smaller spaces. Like all Canon L-series lenses, this telephoto zoom is dust and moisture
resistant and designed to keep on going even in the most challenging of environments.
