Canon has introduced its new EF 70-200mm f/2.8L IS II USM telephoto lens, the successor to the highly regarded initial version of the lens. The body structure of the new lens has been enhanced to provide better durability and strength without a significant increase in weight (1490 grams compared to 1470 grams for the previous version).

Canon has improved the optical performance by redesigning the internal elements, incorporating a fluorite element and a fifth UD element to help minimize secondary chromatic aberrations and produce better image quality with improved contrast and resolution through the entire zoom range. The new lens design features improved auto focus speed due to a new focusing algorithm and a shorter minimum focusing distance of 3.9 feet (1.2 meters). It also features improved image stabilization allowing it to compensate for shutter speeds up to four steps slower than 1/focal length, a one step improvement over the previous lens model.

The new lens retains Canon's protective seals and fittings providing dust and water resistance. A new bayonet mount on the front of the lens includes a locking mechanism to ensure the supplied lens hood remains securely in place. Other improvements include a wider focusing ring and sleeker design achieved by reducing the thickness of any protruding elements such as the switch panel. The new lens is compatible with Canon's existing EF1.4X II and EF2X II Extenders as well as EF Extension Tubes and the 77mm Close-Up Lens 500D.

Pricing and availability
The Canon EF 70-200mm f/2.8L IS II USM lens is supplied with a detachable tripod collar, a reversible bayonet mount lens hood and a lens pouch. The new lens is scheduled to be delivered to U.S. dealers in April, at a price to be determined later.
