Product description

If you don''t have a telephoto zoom lens in your arsenal, this is a great place to start. The superb multi-purpose SAL-DT55200 55-200mm f4-5.6 telephoto zoom lens is an excellent all-around value, covering the medium to long-distance telephoto range you will use most. It also provides close minimum focusing distance of about 3 feet (.95m), for tight shots of people, natural subjects and close-up details. Its compact, lightweight design makes it easy to carry as your standard or accessory lens - and all your shots will benefit from the Sony Super SteadyShot image stabilization system built into every Sony a system DSLR. (35mm equivalent: 82.5-300mm). Please note: DT lenses are not recommended for use with the DSLR-A900.

Compact Design, All-Around Versatility
This high-value 55-200mm zoom lens covers a wide range of medium to long-distance telephoto applications -- and its lightweight design lets you leave it on-camera or carry it easily as an accessory lens for special purposes (35mm equivalent: 82.5-300mm).

DT Lens Design
The SAL-DT55200 is specially designed for the APS-size CCD imager used in Sony & 945 (alpha) DSLR cameras. APS-size sensors are smaller than a 35mm-format film frame, so the focal distance to cover the same field of view can be about 2/3 shorter -- allowing a more compact lens design.

Short Minimum Focusing Distance
With the ability to focus as closely as 3 feet (.95m), this telephoto lens also lets you move in for dramatic shots of people, natural subjects and close-up details.

In-Camera Image Stabilization
A major reason for its compact, lightweight design is the benefit of Super SteadyShot in-camera image stabilization, built into every Sony & 945 system DSLR -- and enabling accessory lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms.

Multi-Element Design
The SAL-DT55200 is designed with 13 lens elements in 9 groups, with precision focusing performFrom the Manufacturer

DT 55-200mm F4-5.6 SAM Zoom Lens

This superb telephoto zoom lens for your α DSLR camera has a smooth and silent AF operation with built-in motor to handle themed range to telephoto zoom shots. In 35mm equivalent, it covers midrange 82.5mm to 300mm telephoto zoom (4x) ideal for shooting portraits, sports, wildlife and more. An excellent all-around lens. Please note: DT lenses are not recommended for use with the DSLR-A900.TechnologyCircular Aperture

When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result. ED (Extra-low Dispersion) glass

As focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and as a result images suffer from lower contrast, lower color quality, and lower resolution. ED glass dramatically reduces chromatic aberration at telephoto ranges, and provides superior contrast across the entire image, even at large aperture settings. Super ED glass provides enhanced compensation for chromatic aberration. Distance encoder

The distance encoder plays an integral part in ADI flash metering, which delivers high precision flash metering that is unaffected by the reflectance of subjects or backgrounds. The distance encoder is a lens component that directly detects the position of the focusing mechanism, and sends a signal to the CPU in order to measure distance to the subject. During flash photography, this data is very useful in calculating how much flash output is appropriate to the scene.SAM (Smooth Autofocus Motor)
