Sony expands α (ALPHA) lens system with the addition of
two high-performance zooms
SAN DIEGO, Jan. 30, 2008 – Sony today announced two new high performance zoom lenses that offer α (alpha) digital SLR camera users more options for high picture quality.
Vario Sonnar T* 24-70mm f/2.8 ZA
Co-developed with Carl Zeiss®, the SAL2470Z model is a wide angle
24-70mm zoom lens with a large f/2.8 aperture, ideally suited for
discerning landscape and portrait photography. Constructed of 17
elements in 13 groups with two aspheric elements and two extra-low
dispersion elements, this lens exhibits excellent contrast and
center-to-edge resolution. Its exclusive Carl Zeiss T* (T star) coating
technology provides higher light transmission, and minimizes flare to
produce images of luminous clarity, color and sharpness.
The SAL2470Z lens excels in difficult lighting circumstances thanks to
its f/2.8 aperture, which remain constant throughout the focal length
range. The nine-blade, circular iris is especially useful in
controlling background defocusing in portrait and landscape images.
Combined with Sony’s in-camera Super SteadyShot® system, this lens is
the only compatible large aperture standard zoom with the benefit of
image stabilization available in the industry.
Quick and precise focusing is delivered by Sony’s Super Sonic wave
Motor (SSM) technology. This SSM system utilizes a solid-state focus
drive motor that features silent, high-speed response with high-torque
and fine rotational control – especially important for large, wide
aperture lenses. A mode selector for manual and automatic focus as well
as a focus hold control is provided on the lens barrel.
70-300mm f/4.5-5.6 G
The SAL70300G lens incorporates the optical performance of Sony’s G
series in a compact and flexible telephoto zoom lens ideal for sports
and portrait photography. Constructed of 16 elements in 11 groups,
with one extra-low dispersion element, this lens offers superb contrast
and sharpness across its wide focal length range.
The use of extra-low dispersion glass compensates for chromatic
aberrations which challenge long telephoto zoom lens design,
maintaining excellent optical characteristics from center to periphery.
Internal focus construction not only realizes compact size, but also a
close focusing capability of just 47 inches (1.2m), unusual for a lens
of this focal length range.
Like the SAL2470Z, focus drive is provided by Sony’s Super Sonic wave
Motor (SSM) technology. Silent and highly accurate, the SSM system is
ideal for providing larger lenses with the speed and rotational
precision often required by telephoto shooting. To match auto focus
operation to the situation, a focus range limiter can be set to a
minimum distance of three meters. A lens barrel mounted focus hold
button locks focus if desired.
Price and Availability
Both lenses will be available this spring. The Vario-Sonnar T* 24-70mm
f/2.8 ZA lens will be available for about $1,750 and the 70-300mm
