EF 70-200mm f/2.8L IS II USM
The Canon EF 70-200mm f/2.8L IS II USM Telephoto Zoom Lens 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 is constructed of 23 elements in 19 groups (including 1 Fluorite and 5 UD elements) which help deliver the sharpness and reduced aberration which professional photographers rely upon from Canon. The IS II Optical Image Stabilizer provides up to 4 stops of correction at all focal lengths.
This lens has a minimum focusing distance of 3.9' (1.2 m) at all zoom settings so you can get the shot when shooting 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.
Rubber O-ring can be combined with EOS 1V and EF "II" teleconverters for near imperviousness to moisture exposure
Two-stage Image Stabilization can correct for all types of camera shake or just up/down shake (for use when panning with a moving subject)
