New Leica 120mm f/2.5 Lens for S2 System

Leica has released its 120mm f/2.5 lens to be used with its flagship S2 medium format camera. The Leica APO-MACRO-SUMMARIT-S 120 mm/f2.5 portrait lens is the fourth lens to be available for the 37.5 megapixels portable mastodon — the 35mm f/2.5, 70mm f/2.5 and 180mm f/3.5 were already available.

The new lens has been designed for portraits, beauty, product and macro photography, says Leica, and is the first “fast macro-telephoto lens with superior imaging quality in the Leica S-System line-up.”

It is composed of nine elements in seven groups, including three elements with anomalous partial dispersion – “two of which are highest-quality fluoride lenses for the correction of chromatic aberration.” The lens is also dust and splash-proofed, says Leica.

The Leica S2 was first unveiled at Photokina in September 2008. At this year’s Photokina, starting Monday, September 20, Leica is expected to announce new products

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.
