Canon EF 400mm f/2.8 IS II USM


Even though fast super-telephoto lenses are known to be notoriously heavy, the new Canon EF 400mm/f/2.8 IS II USM, even at 8.49 lb, is more than 28% lighter than its predecessor, making it one of the lightest in its class.

The new Canon EF 400mm f/2.8L IS USM lens, which is expected to be available in December, 2010, for an approximate retail price of $11,000, also features an improved image-stabilization system designed to enable a 4-stop advantage over camera shake when shooting handheld or on a tripod, Fluorite lens elements (in a total of 16 elements in 12 groups), Fluorine coatings and an inner focusing system with focus-assist cams.

Other features include a 6-degree field of view, a minimum focusing distance of 8.86' (2.7m), and 52mm rear drop-in filters
