Two New Canons Telephoto Lens

Canon Inc. announced that it is developing two new telephoto lenses for use with its EOS lineup of single-lens reflex cameras: the EF500mm f/4L IS II USM and EF600mm f/4L IS II USM. They will display the prototypes at the Photokina 2010, between September 21 and 26 in Cologne, Germany.

Both are being developed as L (Luxury)-series lenses equipped with a high-performance stabilization system. Employing fluorite and other special optical materials to correct for a variety of aberrations, the lenses aim to realize high-resolution, high-contrast imaging performance –from the maximum aperture setting– in a lighter-weight body design.

As the successors to the EF500mm f/4L IS USM (introduced in July 1999) and EF600mm f/4L IS USM (introduced in September 1999), the new lenses target improved dust-proof and moisture-proof performance in the face of harsh shooting conditions to satisfy the demands of sports, news and nature photographers.
