Two New Sony Lenses

September 11, 2008: Coincident with the unveiling of the DSLR-A900 camera, Sony has also released details of two new lenses: the SAL1635ZA and SAL70400G.
The SAL1635ZA Vario-Sonnar T* 16-35mm f/2.8 ZA is a Carl Zeiss design that provides a super-wide zoom on the A900. Constructed from 17 elements in 13 groups, it features an ED (extra-low dispersion) element to improve optical clarity and centre-to-edge resolution plus a super ED glass element for much stronger correction of chromatic aberration and accurate colour rendition. Three aspherical lens elements provide greater brightness across the image field, while Carl Zeiss T* (T star) coating technology enhances light transmission and minimises flare and ghosting.

The SAL70400G is the latest addition to Sony’s G-series line of premium lenses. Offering a focal length range of 70-400mm it provides a 5.7x zoom ratio. Maximum apertures range from f/4 to f/5.6. Consisting of 18 elements in 12 groups, it includes two ED glass lenses and boasts a circular aperture with nine diaphragm blades for pleasing de-focused effects. At the minimum focus distance of 1.5m, maximum magnification is 0.27x. Internal focusing allows use with angle-critical filters and attachments, while a focus mode switch and three focus hold buttons have been added to the lens barrel for enhanced operability.

Both lenses include Sony’s Super Sonic wave Motor (SSM) autofocus drive system, which provides fast, precise and quiet autofocusing. Both models can be used with all Sony Alpha DSLR cameras where they benefit from the in-camera SteadyShot Inside image stabilisation system. Both lenses are scheduled for release early in 2009.
