EN: Canon will show two new telephoto lenses under development
Canon announced that is in development of 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-and will display prototypes at the photokina 2010 photography and imaging industry trade fair between September 21 and 26 in Cologne, Germany.
The EF500mm f/4L IS II USM and EF600mm f/4L IS II USM are being developed as L (Luxury)-series lenses equipped with a high-performance image 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 in a lighter-weight body design.
The EF500mm f/4L IS II USM and EF600mm f/4L IS II USM are under development as successors to the EF500mm f/4L IS USM (introduced in July 1999) and EF600mm f/4L IS USM (introduced in September 1999), respectively, models which earned strong praise from professionals in the field. 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.
