Sony SAL-55200 review
Sony’s SAL55200 55-200mm f4-5.6 Telephoto Zoom Lens for ?™ (alpha)
Digital SLR Cameras.
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 ? (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 ? 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 performance and smooth zoom operation.
ED (Extra-low Dispersion) Glass - Because light of different wavelength (or
color) bends at different angles when it passes through a lens, ED
(Extra-low Dispersion) Glass is used to eliminate chromatic aberration by
correcting certain wavelengths of light for sharp, clear images with well
defined colors.
