Canon EF 300mm f/2.8L IS II USM
According to Canon, the new Canon EF 300mm f/2.8L IS II USM is 8% lighter and measurably faster than its predecessor, with improved image-stabilization characteristics, which should capture the attention of sports and action shooters alike.
The Canon EF 300mm f/2.8L IS USM lens is expected to be available in December, 2010, for an approximate retail price of $7,000. The lens is a fast, high performance fixed focal length telephoto that incorporates Fluorite glass elements, Fluorine and other advanced coatings and an advanced 3-mode image stabilization system designed to better guarantee sharp imagery regardless of where you're shooting, what you're shooting or whether the lens is handheld or mounted on a tripod. The new Canon EF 300 f/2.8L IS II USM contains 16 Fluorite elements in 12 groups, rear drop-in filters (52mm), USM focusing motors, and close focusing down to 6.6' (2m).
