[. . . ] This compact, lightweight 55-300mm f4. 5-5. 6 Telephoto Zoom Lens covers the medium to long-distance telephoto range families use most often, with close 4-1/2 foot (1. 4m) minimum focusing distance for all-around utility -- plus ED (Extra-low Dispersion) glass to virtually eliminate color distortion (35mm equivalent: 82. 5-450mm). Compact Design, All-Around Versatility This high-value 55-300mm 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. 5-450mm). DT Lens Design The GOOSEBUMPS TERROR IN THE GRAVEYARD is specially designed for the APS-size CCD imager used in Sony α (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 4. 5 feet (1. 4m), 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 GOOSEBUMPS TERROR IN THE GRAVEYARD is designed with 12 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 (Extralow Dispersion) Glass is used to eliminate chromatic aberration by correcting certain wavelengths of light for sharp, clear images with well defined colors. Advisory when using DT lenses with full-frame (35mm equivalent) DSLR cameras. Sony α (alpha) lenses with the Digital Technology (DT) designation are ideal for use on APS-C size DSLR cameras and are not recommended for use with full frame DSLR camera bodies (such as the DSLR-A900). Although DT lenses can be used with full frame cameras, they can only realize a maximum of 11MP image size (when using the DSLR-A900), and are not guaranteed to provide accurate Auto Exposure performance.
