Canon announced the highly anticipated Canon EF 100- 400mm f/4.5-5.6L II USM, a second generation compact super-telephoto zoom lens. This is a replacement for Canon’s EF 100-400mm f/4.5- 5.6L, which was launched in 1998. The EF 100-400mm f/4.5-5.6L IS II USM includes one Fluorite and one Super UD element. Also introduced is a new ASC (Air Sphere Coating) technology, which uses suspended air bubbles in the coating. The design reduces ghosting and flare. The lens has a rotating zoom design instead of the earlier ‘push-pull’ design, to mitigate the problem of dust being sucked in every time you zoom in. It also offers three Image Stabilization (IS) modes, with 4 stops of stabilization, and automatically locks IS when a tripod is in use. The minimum focus distance is 3.2 feet and the lens offers 0.31x maximum magnification. A new bayonet-style ET-83D hood is included, with a slot for easier adjustment of certain filters.
