Pre-Photokina 2008: Alongside the A900 announcement, Sony has introduced two new high-end lenses to augment its full-frame lens range. The addition of the Carl Zeiss Series 16-35mm F2.8 and G Series 70-400 F4-5.6 means Sony now offers premium grade zooms all the way from 16mm to 400mm. The 16-35mm complements the recently introduced Carl Zeiss Series 24-70mm F2.8 and means F2.8 zooms are available from 16mm to 200mm. Both the new lenses feature customizable AF stop buttons that can operate the A900's 'Intelligent Preview' function.

Press Release:

New Premium Lenses Support Full-Frame Alpha DSLR Camera

SAN DIEGO, Sept. 9, 2008Sony is expanding its number of high performance Carl Zeiss® and G Series lenses with the addition of the new SAL1635ZA and SAL70400G models.

Vario Sonnar T* 16-35mm f/2.8 ZA Carl Zeiss Series Lens
The SAL1635ZA model is a super wide angle 16-35mm f/2.8 constant aperture zoom lens, well-suited for landscape, snapshot and indoor photography. 

It is constructed of 17 lens elements in 13 groups, including an extra-low dispersion (ED) for exceptional clarity and center-to-edge resolution and a super ED glass element for much stronger correction of chromatic aberration or discoloration. It also features three aspherical lens elements that provide greater brightness from center to the edge of the image field.Its Carl Zeiss T* (T star) coating technology provides higher light transmission, and minimizes flare to produce images of luminous clarity, color and sharpness.

The SAL1635ZA lens offers the utmost flexibility in challenging lighting conditions due to its wide f/2.8 constant aperture. Combined with Sony’s in-camera SteadyShot® Inside image stabilization system, this lens is the only large aperture, full-frame capable, wide-angle zoom lens with the benefit of stabilization in the industry.

Smooth, fast and precise focusing is delivered by Sony’s Super Sonic wave Motor (SSM) autofocus drive system. It utilizes a solid-state focus drive motor to provide silent, high-speed response, powerful torque and fine rotational control – critically important for large wide-aperture lenses.

70-400mm f/4-5.6 G Series Lens
The SAL70400G lens is a 5.7x super telephoto zoom lens and the latest addition to Sony’s G-series line of premium lenses. Designed to deliver extremely sharp descriptive performance across its wide focal length range, it is ideally suited for sports, action and wildlife photography.

Constructed of 18 elements in 12 groups, it includes two extra-low dispersion glass lenses for high contrast, sharp details, and exceptional center-to-edge resolution with minimal chromatic aberration. A circular aperture with nine diaphragm blades is utilized to achieve natural, aesthetically-pleasing de-focusing effects.

With a minimum focus distance of 1.5m and maximum magnification of 0.27x, the lens delivers best-in-class performance.Like the SAL1635ZA lens, focus drive is provided by its SSM system, which offers the speed and rotational precision often required for telephoto shooting. Additionally, the lens has an internal focusing system for faster auto focusing.

A focus-mode/range switch and three focus-hold buttons have been added to the lens barrel for enhanced operability.

For both models, when attached to the flagship α900 camera body, the AF hold buttons can be customized to activate the intelligent preview function.

Price and Availability
The Vario-Sonnar T* 16-35mm f/2.8 ZA and 70-400mm f/4-5.6 G lens will ship in January 2009 for about $1,800 and $1,500, respectively. They will be available at sonystyle.com, at Sony Style® retail stores (www.sonystyle.com/retail), at military base exchanges, and at authorized dealers nationwide.
